Sherman, the former U.S. deputy secretary of state, says “we must persist” in pursuing a diplomatic solution to the impasse over Iran’s nuclear program.

U.S. President Donald Trump claims that Israeli and U.S. strikes “obliterated” Iran’s nuclear program but other experts were more cautious.

The U.S. decision to join Israel’s strikes on Iran’s safeguarded nuclear facilities while negotiations on a nuclear agreement were ongoing dealt a serious blow to U.S. efforts to constrain Iran’s nuclear program. The premature use of force set back Iran’s nuclear program temporarily, but risks pushing Tehran closer to nuclear weapons in the long term. The U.S. strikes also complicate the diplomatic efforts that are still necessary to reach an effective, verifiable nuclear deal.

Israel's strikes on Iran, beginning on June 13, 2025, include the targeting of nuclear facilities. The United States also targeted three nuclear facilities on June 21.

President Donald Trump’s decision to join Israel’s illegal attacks against the Iranian leadership, civilian targets, and the country's major nuclear sites represents an irresponsible departure from Trump’s pursuit of diplomacy and increases the risk of a nuclear-armed Iran.

President Donald Trump is reportedly considering direct U.S. military intervention in support of Israel’s illegal attacks against the Iranian leadership and the country's major nuclear sites. U.S. strikes would represent an abrupt and irresponsible departure from Trump’s pursuit of diplomacy and set back efforts to reach an effective nuclear agreement.  

To reach an effective non-proliferation deal with Iran, the U.S must abandon zero enrichment of uranium as a requirement. Unless Trump is willing to show more flexibility and realism regarding the future of Iran’s nuclear activities, the United States will miss another opportunity to address Iran's growing proliferation risk.

U.S. President Donald Trump voiced optimism about a possible Iran nuclear deal, but there still appear to be significant differences over the scope of the agreement. 

The IAEA’s May 2025 evaluation of Iran's nuclear activities underscore the urgent need for a nuclear deal that brings Iran back into compliance with its legally binding safeguards obligations and limits its future proliferation risk. 

The United States and Iran held three constructive rounds of negotiations over Iran’s nuclear program, but comments from Washington and Tehran suggest that key differences remain.

Trump administration officials have sent mixed messages about U.S. objectives for a nuclear deal with Tehran. 

U.S. President Donald Trump said he told Iran’s supreme leader, “I hope you’re going
