Vice President JD Vance on Tuesday warned that President Donald Trump may “take further action” to stop Iran from developing a nuclear weapon, and urged people who don’t support such action to trust the president.

Trump “may decide he needs to take further action to end Iranian enrichment,” Vance wrote in a post on X. “That decision ultimately belongs to the president.”

Iran has increased its uranium enrichment to near weapons-grade levels, according to a report from a United Nations nuclear watchdog. The country has been the subject of Israeli bombardment in recent days over its refusal to give up its nuclear capabilities.

The Trump administration has attempted to negotiate a nuclear deal with Iran in recent months but talks halted after Israel struck Tehran last week.

“Iran should have signed the ‘deal’ I told them to sign,” Trump wrote on Truth Social Monday. “What a shame, and waste of human life. Simply stated, IRAN CAN NOT HAVE A NUCLEAR WEAPON. I said it over and over again! Everyone should immediately evacuate Tehran!”

Vance, in an attempt to appease both the MAGA war hawks and isolationists within Trump’s base, the latter of which he’s been a committed member, validated the concern about getting involved in a foreign war. “People are right to be worried about foreign entanglement after the last 25 years of idiotic foreign policy.”

But he stressed that Trump “has earned some trust on this issue,” and “having seen this up close and personal, I can assure you that he is only interested in using American military to accomplish the American people’s goals. Whatever he does, that is his focus.”

The comments come hours after Trump made an abrupt departure a day earlier than scheduled from the G7 summit in Canada.

French President Emmanuel Macron said Trump left the conference to negotiate a ceasefire between Israel and Iran. But the president took to Truth Social to correct his French counterpart.

“Wrong!” he said. “He has no idea why I am now on my way to Washington, but it certainly has nothing to do with a Cease Fire.”

The reasoning is “much bigger than that,” Trump said.
