Under US law, President Donald Trump faces an impending deadline to end military operations against Iran. The 1973 War Powers Resolution stipulates that a US president can only launch a war without congressional approval for a period of 60 days. Once that window closes, Congress must either formally declare war or authorize the military action, or the president is required to cease all operations.
The 60-Day Clock
The clock began ticking when Trump ordered strikes on Iranian targets following escalating tensions. As of late April 2026, the 60-day mark is approaching rapidly. If Congress does not act, Trump must withdraw forces and end hostilities. However, the president has shown no indication of backing down, raising questions about the consequences of ignoring the law.
What Happens If Trump Ignores the Deadline?
Legal experts suggest that ignoring the War Powers Resolution could trigger a constitutional crisis. The law was enacted to check presidential power after the Vietnam War, but its enforcement remains untested. Potential outcomes include:
- Congressional action: Lawmakers could sue the administration or pass a resolution demanding withdrawal.
- Funding cuts: Congress could refuse to appropriate funds for continued operations.
- Impeachment: Some Democrats have hinted at impeachment proceedings if Trump defies the law.
However, past presidents have often circumvented the resolution by arguing that their actions do not constitute "war" or by seeking retroactive approval. Trump's administration may similarly claim that the operations are limited and do not require a formal declaration.
Historical Precedents
The War Powers Resolution has been controversial since its inception. Presidents from both parties have frequently ignored its provisions, citing national security needs. For instance, President Obama's intervention in Libya in 2011 exceeded the 60-day limit without congressional approval, yet no legal action was taken. Similarly, President Biden's airstrikes in Syria in 2021 were not formally authorized by Congress.
Trump's case, however, is unique due to the scale of operations and the explicit threat of a wider conflict with Iran. The situation is further complicated by political divisions in Congress, where Republicans largely support the president while Democrats demand adherence to the law.
International and Domestic Reactions
Allies have expressed concern over the potential for escalation, while adversaries like Russia and China have condemned US actions. Domestically, anti-war protests have grown, and advocacy groups are preparing legal challenges. The media has focused on the deadline, amplifying public scrutiny.
If Trump ignores the deadline, the Supreme Court may ultimately decide the issue. However, the court has historically been reluctant to intervene in matters of war powers, leaving the political branches to resolve the dispute.
What's Next?
As the deadline approaches, all eyes are on Congress. A bipartisan group of senators has introduced a resolution to force a vote on ending hostilities, but its prospects remain uncertain. Meanwhile, Trump has vowed to "protect American interests" and hinted at expanding operations. The coming days will test the limits of executive power and the resilience of US democratic institutions.
