President Donald Trump has abruptly canceled a planned diplomatic mission by senior advisers Jared Kushner and Steve Witkoff to Pakistan, effectively halting a second round of negotiations aimed at brokering a long-term peace agreement with Iran, according to reporting from Lex 18 News.

Trump announced the cancellation in a phone interview with Fox News, stating "We have the cards. They can call us anytime they want, but you're not going to be making any more 18-hour flights to sit around talking about nothing." The abrupt decision came after an initial round of talks hosted by Pakistan, which included Vice President JD Vance but did not yield a long-term agreement.

The cancellation reflects growing tension in negotiations between the U.S. and Iran. Trump has previously stated he is awaiting a formal proposal from Iran and expressed skepticism about the country's political leadership following airstrikes that killed Supreme Leader Ali Khamenei and other high-ranking officials earlier this year.

The U.S. has established several preconditions for any agreement, including Iran's abandonment of its nuclear program and the reopening of the Strait of Hormuz, a critical waterway through which approximately 20 percent of the world's fuel supply flows. Iran, however, has expressed distrust of U.S. intentions, citing the American-led blockade of Iranian ports as a violation of the original ceasefire agreement that followed initial joint operations with Israel on Feb. 28.

Defense Secretary Pete Hegseth reported Friday that 34 ships have been turned back since the blockade began, stating "The blockade is tightening by the hour. We are in control. Nothing in, nothing out." Hegseth also reiterated Trump's earlier warning that U.S. forces would engage vessels attempting to lay mines in the Strait of Hormuz.

The diplomatic standoff underscores the widening gulf between the two nations as negotiations stall and military tensions persist in the region.
