Why This Conversation Matters
The recent Israeli attacks on Iran reignited the contentious discourse regarding the moral and legal implications surrounding the doctrine of anticipatory self-defense. Based on the recognized international legal principles, but vaguely referenced in Article 51 of the United Nations Charter, it legitimizes the use of force by states in reaction to an imminent armed assault. Nonetheless, in reality, powerful nations have misused this doctrine to justify unilateral military actions under the pretense of preemption.
This article contends that the United States and Israel have frequently invoked anticipatory self-defense not as a final measure, but as a political tool for legitimizing military operations that contravene the principles of international law. Examining instances from the Cuban Missile Crisis to the Six-Day War, from Operation Opera to the post-9/11 invasions of Afghanistan and Iraq, these examples expose a concerning trend: Anticipatory self-defense has transitioned from a protective measure into a legal pretext for achieving strategic dominance.
The inability of international bodies—especially the UN Security Council—to effectively challenge such actions has further weakened global standards, undermining the legal framework established to avert the arbitrary use of force.
When Self-defense Becomes a Smokescreen
The doctrine of anticipatory self-defense deals with using force in response to imminent threats. Proponents of this doctrine argue about the destructiveness of the latest combat technologies. According to them, states have employed cutting-edge defense systems that will lead to absolute obliteration even before retaliation.
It is asserted that in the presence of nuclear weapons, a state cannot withstand the first attack from the enemy. Hence, the lethality of modern military technologies necessitates the first strike. However, eminent political scholars such as Noam Chomsky called it an imperialistic tool to maintain geopolitical dominance. In his book Hegemony or Survival, Noam Chomsky criticized the Bush doctrine of preemption as “the doctrine of pre-emptive war adopted by the Bush administration is simply a return to the law of the jungle.”
Nevertheless, the question of the legality of this doctrine remained contentious, with innumerable different perspectives. Self-defense in international law is designed merely to resist an armed attack when all other means of negotiations have been exhausted. However, by no means does it justify the initiation of an attack.
The idea of anticipatory self-defense has evolved after 1945 and has been utilized incessantly by Israel and the US to excuse their actions. Regarding these actions, the United Nations has always remained silent. This deafening silence goes against the mandate of the UN. This complacency makes the UN complicit in the actions of the US and Israel.
Case Study I: The Cuban Missile Crisis
In the Cuban Missile Crisis, the US president received vague intel about the USSR’s transport of ballistic missiles to Cuba. The USA established a naval blockade in international waters to cease this operation. Those actions directly violated international law, advocating against the use of force. However, the USA weaponized the doctrine of pre-emptive self-defense to fortify its actions.
Notwithstanding, the USSR and Cuba argued that the missiles were defensive. However, the failure of the UN to bring forth any resolution elucidated that the council members were complicit in the actions of the US. Therefore, this inaction of the UN and its member states legitimized the doctrine of preemptive self-defense.
Case Study II: Six-Day War (1967)
In addition to that, if we analyze the Middle East War in 1967, we can understand that the silence of the United Nations is culpable for not giving a clear interpretation of the charter. It gave the aggressor states authorization to exonerate their actions. On June 5, 1967, the Israeli forces launched attacks against the combined Arab forces of the United Arab Republic (UAR) and promptly subdued their forces.
Although the Arab forces initiated no armed attack, Israel believed that its actions were a legitimate practice sanctioned as the right of self-defense. According to the Israeli authorities, prior actions of Arab states against Israel indicated that an armed attack was imminent. Notwithstanding, these alleged actions of Arab states included amassing large numbers of troops across the Israeli border. This assemblage of troops across borders does not lawfully constitute an imminent threat to the sovereignty of any state. Yet, Israel attacked the UAR and faced no repercussions for its reprehensible actions.
Case Study III: Operation Opera, Bombing of Osirak Reactor (1981)
Not long after the Six-Day War, in 1981, Israel launched Operation Opera and bombed an Iraqi nuclear reactor—the Osirak reactor. Israel claimed that the attack was a lawful exercise of Israel’s inherent right of self-defense. The UK, Malaysia, Uganda, and Nigeria supported the stance of Israel. They took the broad view of self-defense. They proposed that the right of preemption could be lawful if the threat was imminent and the other modes had been exhausted.
Nevertheless, later it was conceded that the pre-emptive strikes by Israel on Iraq’s Osirak reactor had miserably failed to meet the requirements of lawful anticipatory self-defense. The action was based on remote speculations of threats from a nuclear reactor that was not functional at the time of the attack. There was neither an imminent threat nor a necessity to launch an attack. Hence, the actions of Israel cannot be termed as anticipatory self-defense.
Case Study IV: Post-9/11 US Doctrine Shift
However, the saga of anticipatory self-defense does not end with the legitimization of Israel’s actions. This doctrine has also been used to cloak the actions of the USA. It is evident from the operations it executed in the aftermath of 9/11. After the disintegration of the Soviet Union in 1991, the Cold War ended, and the world became unipolar. Therefore, the United States of America emerged as the world’s superpower.
Subsequently, the USA started exerting force on other states, driven by its desire to maintain its global hegemony. However, it concealed its hegemonic actions as acts done in anticipation of future threats. The bombing campaign of America in Afghanistan was a step forward in that direction. Nonetheless, world politics changed its course after 9-11, a terrorist attack on the World Trade Center and the Pentagon in America. The US held Afghanistan responsible and launched an anticipatory attack to protect its sovereignty.
Anticipatory self-defense was acknowledged after the US intervention in Afghanistan. Thus, its scope was broadened post 9/11, due to the countenance of the international community to the US. Additionally, the international abidance of the actions of the USA was an endorsement of the judgment of the ICJ in the Corfu Channel (United Kingdom of Great Britain and Northern Ireland V Albania).
In particular, the court proclaimed that the states were under an obligation not to let the terrorists use their territories against the national interests of another state. Therefore, the US started targeting terrorist groups in Afghanistan. This campaign of the US garnered great support from NATO as well as other Muslim countries. It is argued that the declaration of the US to fight the war on terror resulted in the normalization of anticipatory self-defense.
Case Study V: The 2003 Invasion of Iraq
The US reposed its focus from the War on Terror to anticipatory self-defense against the countries it believed were harboring weapons of mass destruction. It labeled those countries as the notorious “Axis of Evil.” Thus, considering this alleged imminent threat posed by the Axis of Evil, it advocated for a change in international law by expanding the concept of anticipatory self-defense to pre-emptive strikes. Furthermore, the US passed a piece of legislation in this context called the “US National Security Strategy of 2002, states should be held responsible for accommodating terrorist groups. This was a departure from the earlier legislation in which states sought to have effective control over terrorist groups.
Since the declaration of Iran, Iraq, and North Korea as the “Axis of Evil” by the US president, the American policymakers kept on looking for excuses to attack this notorious axis. The US stakeholders tried to pin Al-Qaeda on the government of Saddam in 2002 in the State of the Union address. George Bush made a revelation regarding Iraq possessing weapons of mass destruction. He asserted that Iraq poses a potential threat to the safety and sovereignty of the world. Thus, the threat needs to be eliminated to preserve global stability. President George Bush said:
“Before September 11, many in the world believed Saddam Hussein could be contained, but weapons of mass destruction and terrorist networks cannot be easily contained. It would take one vial, a canister, and one crate slipped into this country to bring a day of horror like none we have ever had before.”
The supporters of the US clarified their positions by stating that the requirement for pre-emptive self-defense has now changed from “imminent threat” to the “possibility of threat.” The US used this new criterion to eliminate the threat posed by Iraq directly or indirectly against itself or its allies. The goal of the US was to use pre-emptive strikes to destroy Iraq’s capability of harboring nuclear weapons.
Russia, France, and Germany challenged the narrative of the US for pre-emptive action against Iraq. These states were not convinced by the US claim that Iraq possessed any weapons. Scholar Richard Falk raised concerns regarding its legality and legitimacy, as no imminence nor necessity suggested the Iraq war, a preventative war.
A Pattern of Power, Not Principle
Consequently, the US government used preemptive self-defense as political rhetoric to garner people’s support. However, the major allies of the US never used preemptive self-defense as their justification for the attacks. They solely relied on the non-compliance with security protocols. These deafening actions raised significant questions about the legality of the doctrine of pre-emptive strikes.
Considering the developments after the end of the Iraq war, it can be said that the entitlement to defend oneself has not yet expanded enough to include pre-emptive strikes. The effort by the US to alter the current regulations regarding the unilateral use of force led other nations to strengthen the existing system. A large majority of international scholars argued that intervention in Iraq could not be justified as self-defense— it could only be called simple aggression. Governments around the world did not accept the justification of the use of force in preventive defense.
Furthermore, the US government itself chose not to justify its action in Iraq based on pre-emptive self-defense. This is a sign that the international community is unwilling to accommodate the arbitrary expansion of the existing doctrine of anticipatory self-defense. However, the USA and Israel are arbitrarily exploiting this doctrine to exculpate their actions. Meanwhile, the quiescence of the United Nations is deplorable and constitutes a grave threat to world peace.
Conclusion
The problematic application of anticipatory self-defense by the US and Israel indicates a concerning decline in international standards. It is a cloak for the aggressive actions of the US and its allies. The US doctrine was not an expansion of the existing doctrine but was designed to suppress states and establish hegemony over the world. Concisely, the doctrine of anticipatory self-defense under Article 51 of the Charter is the right of every state if there is a threat.
However, interchanging it with the possibility of threat and initiating attacks against countries is illegal and against the charter of the UN. The inaction of the United Nations has reinforced this misapplication, converting a protective principle into a rationale for aggression. Therefore, the attacks of Israel on Iran, Yemen, Lebanon, Syria, and Gaza are not acts done in self-defense— they represent breaches of the very order that international law aims to protect.
Even though these actions look innocuous, they have real-world repercussions. It is undermining the regional stability of the whole Middle East, plunging the entire world into a state of conflict. Therefore, the United Nations needs to take prompt action against the US and Israel to protect the world order before it is too late.
