Trump’s May 1 Deadline: Can He Continue War on Iran After That?

As President Donald Trump extends the temporary ceasefire with Iran, a major legal and political deadline is approaching in Washington. Under the 1973 War Powers Resolution, Trump must secure congressional approval by May 1 to continue military operations beyond 60 days. With tensions rising in the Strait of Hormuz and Congress deeply divided, the future of US-Iran conflict remains uncertain.

President Donald Trump is facing growing pressure over the future of the United States’ military operations against Iran as a key legal deadline approaches on May 1.

Although Trump recently announced an extension of the ceasefire with Iran, he did not specify when negotiations would resume. Instead, he said the United States would continue its naval blockade and wait for Tehran’s response for further talks.

However, beyond the battlefield, Trump must also confront an important constitutional issue at home. Under the 1973 War Powers Resolution, often called the War Powers Act, the president must receive congressional approval to continue military action after 60 days unless Congress grants formal authorization.

Without that approval, Trump could be required to scale back or end US military operations against Iran.

What Is the War Powers Act?

The War Powers Resolution was passed in 1973 to limit the power of US presidents to involve the country in overseas armed conflicts without congressional consent.

Under this law, the president must notify Congress within 48 hours of starting military action. Military deployments can continue for only 60 days unless Congress approves a longer commitment or grants a single 30-day extension due to unavoidable military necessity.

Legal experts say that after this 90-day maximum period, the president is expected to terminate military operations if Congress has not declared war or passed formal authorization.

Maryam Jamshidi, an associate professor of law at Colorado Law School, explained that the president must submit written certification to Congress if he wants the additional 30-day extension.

She also noted that while the law is clear in theory, enforcement remains difficult. Several past presidents have argued that parts of the War Powers Resolution are unconstitutional and have continued military operations without fully complying.

Can Trump Get Congressional Approval?

At the moment, congressional approval for extended military action against Iran remains uncertain.

The US Congress is sharply divided between Republicans and Democrats over Trump’s Iran policy. On April 15, a bipartisan Senate effort to restrict Trump’s authority under the War Powers Resolution failed by a narrow 52-47 vote, with most lawmakers voting along party lines.

Democratic Senator Chris Murphy criticized Republican leadership for avoiding oversight of what he described as a war costing billions of dollars each week.

Many Republican lawmakers have supported Trump’s initial military response but insist that longer military engagement must be approved by Congress.

Republican Senator John Curtis said he supports the president’s actions to defend American interests, but he would not support military operations beyond the 60-day limit without congressional authorization.

Congressman Don Bacon also stated that if Congress does not approve continued operations, US forces must stop under the law.

This creates a difficult political environment for Trump, especially as concerns grow over a long and expensive conflict ahead of midterm elections.

Has the Fighting Really Stopped?

Although both Washington and Tehran agreed to a temporary ceasefire on April 8, military pressure has continued, particularly in strategic maritime zones.

The US imposed a naval blockade on Iranian ports on April 13. Days later, US forces intercepted and captured the Iranian-flagged container ship Touska in the northern Arabian Sea near the Strait of Hormuz.

Trump said the vessel ignored US instructions to change its route while heading toward Bandar Abbas.

Iran quickly responded by seizing two foreign commercial ships in the Strait of Hormuz and moving them to its coastline.

Reports also indicated that US forces intercepted multiple Iranian-flagged tankers near India, Malaysia, and Sri Lanka, redirecting them away from sensitive waters.

These developments suggest that while open warfare may have paused, military confrontation continues through naval operations and economic pressure.

Will Trump Continue the War?

Political analysts believe Trump is likely to continue some form of pressure against Iran despite growing domestic opposition.

Salar Mohandesi, a professor of history at Bowdoin College, said the conflict has become politically damaging for Trump because public opinion polls show many Americans oppose the war.

Trump had promised voters he would avoid new wars and secure a stronger deal with Iran. Continuing a prolonged conflict could hurt his political image before the upcoming midterm elections.

However, analysts say Trump’s political style makes retreat difficult.

His public image is strongly tied to projecting strength and winning. Walking away without a clear victory could be seen as political defeat.

Because of this, experts believe Trump may continue escalating pressure in hopes of securing a strategic win rather than accepting compromise.

Can Trump Bypass Congress?

Even if Congress refuses formal approval, Trump may still rely on other legal justifications to continue military operations.

One major option is the Authorization for Use of Military Force, known as the AUMF.

The first AUMF was passed in 2001 after the September 11 attacks to support the US war on terror. Another was passed in 2002 to authorize military action against Iraq and Saddam Hussein.

Successive presidents have used these authorizations to justify military actions far beyond their original purpose.

During his first term, Trump used the 2002 AUMF to justify the 2020 killing of Iranian General Qassem Soleimani in Baghdad.

Former President Barack Obama also relied on the 2001 AUMF to expand military operations against ISIS in Iraq and Syria.

This means Trump could argue that current operations against Iran fall under existing military authorization, even without fresh congressional approval.

How Have Previous Presidents Avoided Congress?

US presidents have frequently conducted military operations without direct congressional approval.

Former President Bill Clinton launched military operations in Iraq, Somalia, and Yugoslavia during the 1990s without formal declarations of war.

In 1999, Clinton ordered military action in Yugoslavia during the Kosovo conflict. The campaign lasted 79 days despite legal challenges arguing he violated the War Powers Resolution.

Similarly, during the 2011 Libya intervention, the Obama administration argued that the mission did not qualify as “hostilities” under the law because there were no sustained active exchanges of fire.

As a result, the administration claimed it did not need formal congressional approval to continue the campaign.

What Happens Next?

As May 1 approaches, Trump faces one of the most significant legal and political tests of his presidency.

If Congress refuses authorization, he must either scale back military action, rely on alternative legal powers, or challenge the limits of the War Powers Resolution itself.

At the same time, tensions with Iran remain high, and the risk of wider regional escalation continues.

Whether Trump chooses diplomacy, continued naval pressure, or deeper military engagement, the next few days could define both US-Iran relations and the balance of presidential war powers in America.
