War (outline) |

A preemptive war is a war that is commenced in an attempt to repel or defeat a perceived imminent offensive or invasion, or to gain a strategic advantage in an impending (allegedly unavoidable) war shortly before that attack materializes. [1] It is a war that preemptively 'breaks the peace' before an impending attack occurs.
Preemptive war is sometimes confused with preventive war: the difference is that a preventive war is launched to destroy the potential threat of the targeted party, when an attack by that party is not imminent or known to be planned. The U.S. Department of Defense defines a preventive war as an armed conflict "initiated in the belief that military conflict, while not imminent, is inevitable, and that to delay would involve greater risk." [2] A preemptive war is launched in anticipation of immediate aggression by another party. [3] Most contemporary scholarship equates preventive war with aggression, and therefore argues that it is illegitimate. [4] The waging of a preemptive war has less stigma attached than does the waging of a preventive war. [5]
Article 2 (4) of the UN Charter requires that states refrain from the initiation of armed conflict, that is being the first to 'break the peace' unless authorized by the UN Security Council as an enforcement action under Article 42. Some authors have claimed that when a presumed adversary first appears to be beginning confirmable preparations for a possible future attack, but has not yet actually attacked, that the attack has in fact 'already begun', however this opinion has not been upheld by the UN. [6] [7]
As early as 1625, Dutch jurist Hugo Grotius characterized a state's right of self-defense to include the right to forestall an attack forcibly. [8] In 1685, the Scottish government conducted a preemptive military strike against Clan Campbell. [9] In 1837, a certain legal precedent regarding preemptive wars was established in the Caroline affair, during which an Anglo-Canadian force from Upper Canada crossed the Niagara River into the United States and captured and burnt the Caroline, a ship owned by Reformist rebels. During the affair, an American citizen was killed by a Canadian sheriff.
The British asserted that their actions were permissible under the international law of self-defense. The United States did not deny that preemptive force might be lawful under some circumstances but claimed the facts did not support its use in this case. U.S. Secretary of State Daniel Webster wrote that when a nation uses force "within the territory of a power at peace, nothing less than a clear and absolute necessity can afford ground of justification" and that the necessity for the use of armed force must be "instant, overwhelming, leaving no choice of means, and no moment for deliberation," which conditions did not apply in this case. [10] That formulation is part of the Caroline test, which "is broadly cited as enshrining the appropriate customary law standard." [11]
The Austro-Hungarian Chief of the General Staff, Franz Conrad von Hötzendorf, argued for a preemptive war against Serbia in 1913. [12] There is however no agreement among historians that Conrad's proposals were preemptive and not preventive. According to other historians, Conrad (a social Darwinist) proposed a preventive war against Serbia more than 20 times before, starting in 1909. [13] Serbia had the image of an aggressive and expansionist power and was seen as a threat to Austria-Hungary in Bosnia and Herzegovina. [12] The assassination of Archduke Franz Ferdinand (June 1914) was used as an excuse for Austria-Hungary to attack Serbia, leading to World War I. [14]
During the course of the destructive and costly World War I, for the first time in history, the concept of "the war to end war" began to be seriously considered. [15] As a further expression of that hope, upon the conclusion of the war, the League of Nations was formed. Its primary aim was to prevent war, as all signatories to the League of Nations Covenant were required to agree to desist from the initiation of all wars, preemptive or otherwise. All of the victorious nations emerging out of World War I eventually signed the agreement, with the notable exception of the United States. [16]
In the 1920s, the League peaceably settled numerous international disputes and was generally perceived as succeeding in its primary purpose. It was only in the 1930s that its effectiveness in preventing wars began to come into question. Such questions began to arise when it first became apparent in 1931 that it was incapable of halting aggression by Imperial Japan in Manchuria. In the Mukden Incident, Japan claimed to be fighting a "defensive war" in Manchuria, attempting to "preempt" supposedly-aggressive Chinese intentions towards the Japanese. According to the Japanese, the Republic of China had started the war by blowing up a South Manchurian Railway line near Mukden and that since the Chinese were the aggressors, the Japanese were merely "defending themselves."' A predominance of evidence has since indicated that the railway had actually been blown up by Japanese operatives. [17]
In 1933, the impotency of the League became more pronounced when notices were provided by Japan and Nazi Germany that they would be terminating their memberships in the League. Fascist Italy shortly followed suit by exiting the League in 1937. [18] Soon, Italy and Germany also began engaging in militaristic campaigns designed to either enlarge their borders or to expand their sphere of military control, and the League was shown to be powerless to stop them. [18] The perceived impotency of the League was a contributing factor to the full outbreak of World War II in 1939. [19] The start of World War II is generally dated from the event of Germany's invasion of Poland. It is noteworthy that Germany claimed at the time that its invasion of Poland was in fact a "defensive war," as it had allegedly been invaded by a group of Polish saboteurs, signaling a potentially-larger invasion of Germany by Poland that was soon to be under way. Thus, Germany was left with no option but to preemptive invade Poland to halt the alleged Polish plans to invade Germany. It was later discovered that Germany had fabricated the evidence for the alleged Polish saboteurs as a part of the Gleiwitz incident.
Once again, during the course of the even more widespread and lethal World War II, the hope of somehow definitively ending all war, including preemptive war, was seriously discussed. That dialogue ultimately resulted in the establishment of the successor organization to the League, the United Nations (UN). As with the League, the primary aim and hope of the UN was to prevent all wars, including preemptive wars. Unlike the League, the UN had the United States as a member.
In analyzing the many components of World War II, which one might consider as separate individual wars, the various attacks on previously-neutral countries, and the attacks against Iran and Norway might be considered to have been preemptive wars.
As for the 1940 German invasion of Norway, during the 1946 Nuremberg trials, the German defense argued that Germany had been "compelled to attack Norway by the need to forestall an Allied invasion and that her action was therefore preemptive." [20] The German defence referred to Plan R 4 and its predecessors. Norway was vital to Germany as a transport route for iron ore from Sweden, a supply that Britain was determined to stop. One adopted British plan was to go through Norway and occupy cities in Sweden. [21] [22] An Allied invasion was ordered on March 12, and the Germans intercepted radio traffic setting March 14 as deadline for the preparation. [23] Peace in Finland interrupted the Allied plans, but Hitler became rightly convinced that the Allies would try again and ordered Operation Weserübung.
The new Allied plans were Wilfred and Plan R 4 to provoke a German reaction by laying mines in Norwegian waters, and once Germany showed signs of taking action, Allied forces would occupy Narvik, Trondheim and Bergen and launch a raid on Stavanger to destroy Sola airfield. However, "the mines were not laid until the morning of 8 April, by which time the German ships were advancing up the Norwegian coast." [24] However, the Nuremberg trials determined that no Allied invasion was imminent and therefore rejected Germany's argument of being entitled to attack Norway. [25]
In August 1941, Soviet and British forces jointly invaded Iran with the aim of preempting an Axis coup. [26]
Israel incorporates preemptive war in its strategic doctrine to maintain a credible deterrent posture, based on its lack of strategic depth. [27] [28] [29] The Six-Day War, which began when Israel launched mass attacks against Egypt on June 5, 1967, has been widely described as a preemptive war [30] [31] [32] [33] and is, according to the United States State Department, "perhaps the most cited example [of preemption]." [34] Others have alternatively referred to it as a preventive war. [35] Some have referred to the war as an act of "interceptive self-defense." [36] According to that view, no single Egyptian step may have qualified as an armed attack, but some perceive Egypt's collective actions as clear that it was bent on an armed attack on Israel. [37] One academic has claimed that Israel's attack was not permissible under the Caroline test; he claims that there was no overwhelming threat to Israel's survival. [38]
The doctrine of preemption gained renewed interest following the American-led invasion of Iraq. The George W. Bush administration claimed that it was necessary to intervene to prevent Saddam Hussein from deploying WMDs. At the time, American decision-makers claimed that Saddam's weapons of mass destruction might be given to militant groups and that the nation's security was at a great risk. Congress passed its joint resolution in October 2002, authorizing the American president to use military force against Saddam's government. [39] However, The Iraq Intelligence Commission confirmed in its 2005 report that no nuclear weapons or biological weapons capability existed. Many critics have questioned the true intention of the administration for invading Iraq, based on possibility of retaliation in the September 11 attacks.
The scholar Abraham David Sofaer identified four key elements for justification of preemption: [40]
Professor Mark R. Amstutz, citing Michael Walzer, adopted a similar but slightly-varied set of criteria and noted three factors to evaluate the justification of a preemptive strike. [41]
The proliferation of weapons of mass destruction by rogue nations gave rise to a certain argument by scholars on preemption. [42] [43] [44] They argued that the threat need not be "imminent" in the classic sense and that the illicit acquisition of the weapons, with their capacity to unleash massive destruction, by rogue states, created the requisite threat to peace and stability as to have justified the use of preemptive force. NATO's Deputy Assistant Secretary General for WMD, Guy Roberts, cited the 1962 Cuban Missile Crisis, the 1998 US attack on a Sudanese pharmaceutical plant, (identified by US intelligence to have been a chemical weapons facility) and the 1981 Israeli attack on Iraq's nuclear facility at Osirak as examples of the counterproliferation self-help paradigm. [45] Regarding the Osirak attack, Roberts noted that at the time, few legal scholars argued in support of the Israeli attack, but he noted further that "subsequent events demonstrated the perspicacity of the Israelis, and some scholars have re-visited that attack arguing that it was justified under anticipatory self-defense." [46] After the US invasion of Iraq in 2003, US forces captured a number of documents detailing conversations that Saddam had with his inner sanctum. [47] The archive of documents and recorded meetings confirm that Saddam Hussein was indeed aiming to strike at Israel. [47] In a 1982 conversation Hussein stated, "Once Iraq walks out victorious, there will not be any Israel." Of Israel's anti-Iraqi endeavors he noted, "Technically, they [the Israelis] are right in all of their attempts to harm Iraq." [47]
After the departure of the Bush administration, the Obama administration adopted and continued many policies of the Bush Doctrine. [48]

The intention with a preemptive strike is to gain the advantage of initiative and to harm the enemy at a moment of minimal protection, for instance, while vulnerable during transport or mobilization.
In his "Rationalist Explanations for War," James Fearon attributes the use of preemptive strikes by rational states to both offensive advantages and commitment problems between states. [49] When a nation possesses a first strike advantage and believes itself to have a high probability of winning a war, there is a narrower de facto bargaining range between it and an opposing country for peaceful settlements. In extreme cases, if the probability of winning minus the probable costs of war is high enough, no self-enforcing peaceful outcome exists. In his discussion of preventative war arising from a commitment problem, Fearon builds an infinite-horizon model expected payoffs from period t on are (pt/(l - δ)) - Ca for state A and ((1 -pt)/(l - δ)) - Cb for state B, where Ca and Cb are costs incurred the respective states and δ is the state discount of the future period payoffs.
The model shows that a peaceful settlement can be reached at any period that both states prefer, but strategic issues arise when there is no credible third-party guaranteer of the two states committing to a peaceful foreign policy. If there is going to be a shift in the military power between states in the future, and no credible restraint is placed on the rising military power not to exploit its future advantage, it is rational for the state with declining military power to use a preventative attack while it has a higher chance of winning the war. Fearon points out that the declining state attacks are caused not by fear of a future attack but because the future peace settlement would be worse for it than in the current period. The lack of trust that leads to a declining power's preemptive strike stems not from uncertainty about intentions of different nations but from "the situation, the structure of preferences and opportunities, that gives one party incentive to renege" on its peaceful cooperation and exploit its increased military potential in the future to win a more profitable peace settlement for itself. Thus, Fearon shows that preemptive military action is taken by nations when there is an unfavorable shift in military potential in the future that leads to a shrinking bargain range for a peaceful settlement in the current period but with no credible commitment by the other party to avoid exploiting its improved military potential in the future.
Article 2, Section 4 of the UN Charter is generally considered to be jus cogens (literally "compelling law" but in practice "higher international law") and prohibits all UN members from exercising "the threat or use of force against the territorial integrity or political independence of any state". However, in the modern framework of the UN Charter, it is the phrase "if an armed attack occurs" in Article 51 [50] that draws the line between legitimate and illegitimate military force. [39] Some scholars believe it is reasonable to assume that if no armed attack has yet occurred that no automatic justification for preemptive 'self-defense' has yet been made 'legal' under the UN Charter. Others conclude that the "inherent right of collective or individual self-defense" in Article 51 includes the preemptive, or anticipatory, self-defense recognized under customary international law, as articulated in the Caroline test'' noted above. (See Self-defence in international law for additional discussion.) In order to be justified as an act of self-defense, two conditions must be fulfilled which are widely regarded as necessary for its justification. The first of these is that actor must have believed that the threat is real, as opposed to (merely) perceived. The second condition is that the force used in self-defense must be proportional to the harm which the actor is threatened. [51]
The Iraq disarmament crisis was claimed as one of the primary issues that led to the multinational invasion of Iraq on 20 March 2003.
The Bush Doctrine refers to multiple interrelated foreign policy principles of the 43rd President of the United States, George W. Bush. These principles include unilateralism, preemptive war, and regime change.
A casus belli is an act or an event that either provokes or is used to justify a war. A casus belli involves direct offenses or threats against the nation declaring the war, whereas a casus foederis involves offenses or threats against its ally—usually one bound by a mutual defense pact. Either may be considered an act of war. A declaration of war usually contains a description of the casus belli that has led the party in question to declare war on another party.
This article describes the positions of world governments before the actual initiation of the 2003 invasion of Iraq, and not their current positions as they may have changed since then.
A United States presidential doctrine comprises the key goals, attitudes, or stances for United States foreign affairs outlined by a president. Most presidential doctrines are related to the Cold War. Though many U.S. presidents had themes related to their handling of foreign policy, the term doctrine generally applies to presidents such as James Monroe, Harry S. Truman, Richard Nixon, Jimmy Carter and Ronald Reagan, all of whom had doctrines which more completely characterized their foreign policy.
A preventive war is an armed conflict "initiated in the belief that military conflict, while not imminent, is inevitable, and that to delay would involve greater risk." The party which is being attacked has a latent threat capability or it has shown that it intends to attack in the future, based on its past actions and posturing. A preventive war aims to forestall a shift in the balance of power by strategically attacking before the balance of power has had a chance to shift in the favor of the targeted party. Preventive war is distinct from preemptive strike, which is the first strike when an attack is imminent. Preventive uses of force "seek to stop another state. .. from developing a military capability before it becomes threatening or to hobble or destroy it thereafter, whereas [p]reemptive uses of force come against a backdrop of tactical intelligence or warning indicating imminent military action by an adversary."
A war of aggression, sometimes also war of conquest, is a military conflict waged without the justification of self-defense, usually for territorial gain and subjugation, in contrast with the concept of a just war.
Hugo Grotius, the 17th-century jurist and father of public international law, stated in his 1625 magnum opus The Law of War and Peace that "Most Men assign three Just Causes of War, Defence, the Recovery of what's our own, and Punishment."
The U.S. rationale for the Iraq War has faced heavy criticism from an array of popular and official sources both inside and outside the United States. Putting this controversy aside, both proponents and opponents of the invasion have also criticized the prosecution of the war effort along a number of lines. Most significantly, critics have assailed the U.S. and its allies for not devoting enough troops to the mission, not adequately planning for post-invasion Iraq, and for permitting and perpetrating widespread human rights abuses. As the war has progressed, critics have also railed against the high human and financial costs.
Humanitarian intervention is the use or threat of military force by a state across borders with the intent of ending severe and widespread human rights violations in a state which has not given permission for the use of force. Humanitarian interventions are aimed at ending human rights violations of individuals other than the citizens of the intervening state. Humanitarian interventions are only intended to prevent human rights violations in extreme circumstances. Attempts to establish institutions and political systems to achieve positive outcomes in the medium- to long-run, such as peacekeeping, peace-building and development aid, do not fall under this definition of a humanitarian intervention.
The use of force by states is controlled by both customary international law and by treaty law. The UN Charter reads in article 2(4):
All members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the purposes of the United Nations.
Chapter VII of the United Nations Charter sets out the UN Security Council's powers to maintain peace. It allows the Council to "determine the existence of any threat to the peace, breach of the peace, or act of aggression" and to take military and nonmilitary action to "restore international peace and security".
A dispute exists over the legitimacy of the 2003 invasion of Iraq. The debate centers around the question whether the invasion was an unprovoked assault on an independent country that may have breached international law, or if the United Nations Security Council authorized the invasion. Those arguing for its legitimacy often point to Congressional Joint Resolution 114 and UN Security Council resolutions, such as Resolution 1441 and Resolution 678. Those arguing against its legitimacy also cite some of the same sources, stating they do not actually permit war but instead lay out conditions that must be met before war can be declared. Furthermore, the Security Council may only authorise the use of force against an "aggressor" in the interests of preserving peace, whereas the 2003 invasion of Iraq was not provoked by any aggressive military action.
Operation Opera, also known as Operation Babylon, was a surprise airstrike conducted by the Israeli Air Force on 7 June 1981, which destroyed an unfinished Iraqi nuclear reactor located 17 kilometres southeast of Baghdad, Iraq. The Israeli operation came a year after the Islamic Republic of Iran Air Force had caused minor damage to the same nuclear facility in Operation Scorch Sword, with the damage having been subsequently repaired by French technicians. Operation Opera, and related Israeli government statements following it, established the Begin Doctrine, which explicitly stated the strike was not an anomaly, but instead "a precedent for every future government in Israel". Israel's counter-proliferation preventive strike added another dimension to its existing policy of deliberate ambiguity, as it related to the nuclear weapons capability of other states in the region.
The legality of the Iraq War is a contested topic that spans both domestic and international law. Political leaders in the US and the UK who supported the invasion of Iraq have claimed that the war was legal. However, legal experts and other world leaders have argued that the war lacked justification and violated the United Nations charter.
Annexation, in international law, is the forcible acquisition and assertion of legal title over one state's territory by another state, usually following military occupation of the territory. In current international law, it is generally held to be an illegal act. Annexation is a unilateral act where territory is seized and held by one state, as distinct from the complete conquest of another country, and differs from cession, in which territory is given or sold through treaty.
Operation Weserübung was the invasion of Denmark and Norway by Nazi Germany during World War II. It was the opening operation of the Norwegian Campaign.
The Caroline test is a 19th-century formulation of customary international law, reaffirmed by the Nuremberg Tribunal after World War II, which said that the necessity for preemptive self-defense must be "instant, overwhelming, and leaving no choice of means, and no moment for deliberation." The test takes its name from the Caroline affair.
The Six-Day War was fought between June 5 and June 10, 1967, by Israel and the neighboring states of Egypt, known then as the United Arab Republic (UAR), Jordan, and Syria. The conflict began with a large-scale surprise air strike by Israel on Egypt and ended with a major victory by Israel. A number of controversies have arisen out of the causes and conduct of the war, namely: whether Israel's action was a preemptive strike justified by the threat of an imminent attack by the Arab states or an unjustified and unprovoked attack; whether the Egyptians killed stragglers from their own forces as they returned from the defeat; whether the Israelis killed unarmed Egyptian prisoners; and the extent of foreign support given to the combatants in the war.
The Russian invasion of Ukraine violated international law. The invasion has also been called a crime of aggression under international criminal law, and under some countries' domestic criminal codes – including those of Ukraine and Russia – although procedural obstacles exist to prosecutions under these laws.
