U.S.-Iran Tensions: Pakistan Mediates New Peace Proposal Amid Congressional War Powers Debate

As of May 3, 2026, a fragile three-week ceasefire between the United States and Iran continues to hold, even as diplomatic and domestic political pressures mount. President Donald Trump confirmed he is reviewing a new proposal from Tehran—delivered via Pakistani mediators—that aims to end the conflict within 30 days. While the proposal seeks a permanent resolution rather than a simple ceasefire extension, the President has expressed public skepticism regarding the likelihood of reaching a final agreement following his rejection of a previous Iranian offer. In Washington, the conflict has triggered a constitutional debate in Congress. Lawmakers are divided over the 60-day limit imposed by the War Powers Act, as U.S. operations have now reached that milestone without formal authorization. President Trump has characterized portions of the Act as "unconstitutional" and suggested the current ceasefire provides the administration additional time to negotiate. Simultaneously, Pakistan has taken a central role in regional diplomacy, with its Prime Minister and Army Chief actively pushing for direct talks between Washington and Tehran. On the ground, maritime tensions remain a significant hurdle. Iranian Deputy Parliament Speaker Ali Nikzad affirmed that Iran will not retreat from its controls over the Strait of Hormuz, rejecting U.S. calls to return to prewar shipping conditions. While no active blockades were reported in the last 24 hours, Tehran is reportedly drafting legislation to formalize restrictions on vessel passage, specifically targeting Israeli-linked ships while requiring others to obtain explicit permission.
