WASHINGTON — President Donald Trump offered mixed messages on Monday about the path ahead for the U.S. war against Iran, declaring that he was in no rush to end the conflict while also expressing confidence that further negotiations with Tehran will soon take place in Pakistan.

With the 14-day ceasefire to expire Wednesday, Trump whipsawed in telephone interviews and social media posts between measured optimism that a deal could soon be reached and warning that “lots of bombs” will “start going off” if there’s no agreement before the ceasefire deadline.

Trump indicated that he still expects to dispatch his negotiating team, led by Vice President JD Vance, to Pakistan’s capital of Islamabad for a second round of talks, even as Iran insisted it would not take part until Trump dialed back his demands.

Iran’s chief negotiator and parliament speaker, Mohammed Bagher Qalibaf, accused the United States of wanting Iran to surrender and added that on the contrary, Iran has been preparing “to reveal new cards on the battlefield.”

“We do not accept negotiations under the shadow of threats,” Qalibaf wrote in a post on X early Tuesday.

Trump insisted he feels no pressure to end the war until Iran agrees to his terms.

“I am under no pressure whatsoever,” Trump said on his Truth Social platform, “although, it will all happen, relatively quickly!”

Pakistani officials moved ahead with preparations for a new round of talks between the U.S. and Iran as the tenuous ceasefire was further strained over the weekend by renewed conflict around the Strait of Hormuz.

Trump told Bloomberg News he was “highly unlikely” to renew the ceasefire.

Iran holds out on resuming talks

Tensions flared after the U.S. Navy attacked and seized a ship on Sunday that it said was trying to evade its blockade of Iranian ports. On Saturday, Iran fired at vessels and abruptly stopped traffic in the strait, abandoning its promise to allow some ships to pass and claiming the U.S. was not holding up its side of the ceasefire.

The U.S. actions are “incompatible with the claim of diplomacy,” Iranian Foreign Minister Abbas Araghchi said Monday in a social media post.

He gave no indication what Iran will do after the ceasefire expires or whether Iran will return to a second round of negotiations with the U.S.

Over the weekend, Iran said it had received new proposals from the U.S. but suggested that a wide gap remains between the sides. Issues that derailed the last round of negotiations included Iran’s nuclear enrichment program, its regional proxies and the strait.

Iran has throttled traffic through the strait, which connects the Persian Gulf to the open seas, since shortly after the U.S. and Israel attacked Iran on Feb. 28 to start the war. The U.S. has also instituted a blockade of Iranian ports. Roughly one-fifth of the world’s oil trade normally passes through the strait.
