Republican lawmakers greeted news of a ceasefire for the US-Israeli war on Iran with polite applause and some scepticism, while their Democratic counterparts called it a monumental defeat for the US.

“A diplomatic solution to end the reign of terror in Iran is the preferred outcome. The supposed negotiating document, in my view, has some troubling aspects, but time will tell,” Republican Senator Lindsey Graham, a close ally of President Donald Trump and early advocate for the war, wrote on X.

Graham said he wanted to ensure the deal ended with Iran not enriching uranium.

“I want to reaffirm that from my point of view, every ounce of the approximately 900 lbs of highly enriched uranium has to be controlled by the US and removed from Iran to prevent them in the future from having a dirty bomb or returning to the enrichment business,” he said.

That statement points to trouble ahead for future talks between Iran and the US, expected to take place on Friday in Islamabad, Pakistan.
