Republican Leaders Voice Sharp Criticism of Trump's Iran Peace Deal

Republican leaders on Capitol Hill, including top national security figures, expressed strong reservations and outright condemnation on Thursday of the Trump administration's agreement to end fighting in Iran. The memorandum of understanding signed by President Donald Trump initiates a 60-day negotiating period to reach a final deal on Iran's nuclear program. The accord includes lifting economic sanctions on Iran's oil sales and establishing a $300 billion fund for Iran's reconstruction and economic development—provisions that drew particular criticism from GOP senators and conservative figures, some of whom are Trump allies.

Senate Armed Services Committee Chairman Roger Wicker of Mississippi expressed concern that intermediaries might be undermining Trump's "peace through strength" approach. He characterized the $300 billion reconstruction fund as far exceeding the financial benefits Iran received under the 2015 nuclear agreement negotiated by the Obama administration, which Trump had withdrawn from during his first term. Texas Senator Ted Cruz, a staunch war supporter, stated bluntly: "History demonstrates giving billions of dollars to the theocratic lunatics who want to kill you is an exceptionally bad idea."

In response, Trump dismissed his critics on Truth Social, calling them "fools" and dismissing reports of U.S. payment as "fake news." He claimed the agreement would bring "Success, Lower Oil Prices, and Victory" to the United States. However, several Republican senators, including Majority Leader John Thune and South Dakota's Mike Rounds, sought clarification on how financial incentives and conditions barring terrorism funding would be enforced.

The criticism from within Trump's own party emerges as he seeks to end the unpopular conflict fewer than five months before midterm elections, where Republicans face challenges maintaining their narrow congressional majorities. Some Republicans aligned with Trump's America First policies offered more measured support. Kansas Senator Roger Marshall highlighted provisions he said strengthen regional security and prevent Iran from obtaining nuclear weapons, while Louisiana GOP candidate John Fleming suggested Trump's agreement implicitly signals readiness to strike Iran again if it fails to comply.
