Legal scholar David Cole has asserted that the current U.S. War on Iran Is “blatantly illegal”, arguing that the military campaign violates both the United States Constitution and the foundational tenets of international law. Cole, a professor of law and public policy at the Georgetown University Law Center and former national legal director of the ACLU, contends that the administration has operated with a willful blindness toward the legal limits of executive power.
The critique centers on the concept of “preventive war”—military action taken to forestall a potential future threat rather than to respond to an imminent attack. Cole argues that the justification for the conflict is a legal fiction, claiming that Iran posed no immediate danger to the United States and that the decision to engage in hostilities was a unilateral move by the president that bypassed essential democratic checks and balances.
At the heart of the dispute is the role of the Justice Department. Cole suggests that the department has either ignored the illegality of recent military actions or provided legal cover through internal memos to justify interventions in Iran and Venezuela. He further alleged a pattern of extrajudicial activity, including the summary execution of over 100 individuals on the high seas, asserting that such actions cannot be justified under any recognized legal framework.
The Violation of International Law and the UN Charter
Under international law, the leverage of force is strictly regulated by the UN Charter. Article 2(4) prohibits member states from using force against the territorial integrity or political independence of another state. You’ll see only two widely recognized exceptions to this rule: when the action is taken in self-defense following an armed attack (Article 51) or when the UN Security Council authorizes the intervention to maintain international peace and security.
Cole argues that neither condition was met in the case of the conflict with Iran. According to Cole, Iran had not attacked the United States, and the UN had not authorized any military intervention. By launching an offensive without these prerequisites, the U.S. Has, in Cole’s view, committed a clear breach of international treaty obligations.
The distinction between “preemptive” and “preventive” war is critical here. Preemptive war is generally viewed as legal if a state can prove an attack is imminent. Preventive war, however, is aimed at preventing a threat from emerging in the distant future. Legal experts generally agree that preventive war is an illegal act of aggression under the UN Charter, as it removes the requirement of an immediate threat.
Constitutional Authority and the War Powers Resolution
Domestically, the conflict raises fundamental questions about the separation of powers. The U.S. Constitution explicitly grants the power to declare war to Congress under Article I, Section 8. While presidents have historically claimed broad authority to conduct limited military actions, Cole argues that the scale and nature of the war in Iran exceed any legitimate executive prerogative.

Cole points to the president’s own rhetoric regarding the limits of his power, noting a previous assertion that only a personal sense of morality—rather than legal statutes—serves as a meaningful constraint on his actions. This “morality-based” approach, Cole argues, is an insufficient substitute for the rule of law and the constitutional requirement for legislative authorization.
Legal Framework Comparison: U.S. Vs. International Law
| Legal Authority | Primary Requirement for Force | Cole’s Assessment of Current War |
|---|---|---|
| UN Charter | Self-defense or UN Security Council authorization | Blatantly illegal. no attack or authorization |
| U.S. Constitution | Congressional authorization/Declaration of War | Blatantly illegal; unilateral executive action |
| Justice Dept. (OLC) | Legal memos justifying “lawful” action | Unjustifiable; “looking the other way” |
Broadening the Scope: Venezuela and High Seas Executions
The legal concerns raised by Cole extend beyond the Iranian conflict. He identified a broader trend of executive overreach, citing military actions in Venezuela as further evidence of a disregard for legal boundaries. These actions, he suggests, mirror the same “preventive” logic used to justify the war in Iran—attacking a perceived adversary before they can act, regardless of whether a legal trigger for war exists.
Most alarming to Cole is the report of summary executions on the high seas. In international law, summary executions—killings carried out without a fair trial or due process—are considered grave violations of human rights and potential war crimes. Cole asserts that the Justice Department’s failure to challenge these actions represents a systemic collapse of legal oversight within the executive branch.
This pattern, Cole argues, creates a dangerous precedent where the president can define “legality” based on personal whim, effectively rendering the Justice Department a rubber stamp for military aggression rather than a guardian of the law.

The next critical checkpoint for these legal challenges will be the upcoming reviews of executive war powers by the federal courts and any potential congressional inquiries into the Justice Department’s legal memos. These proceedings will determine whether the current military strategies will be upheld or designated as unauthorized acts of aggression.
