Republican Congressman Thomas Massie of Kentucky has criticised US military involvement in the conflict with Iran, arguing it has left America significantly weakened. The comments, posted on social media, add to a growing rift within the Republican Party over the Trump administration's handling of Iran, with Massie positioning himself as a vocal critic of the intervention.

In a post on X on Sunday, Massie said the United States "has been significantly weakened by the war with Iran," claiming the administration had depleted missile defences, drained oil reserves, and sacrificed American service members' lives, while also driving up costs, which he suggested was done for Israel's benefit. His remarks come amid wider Republican debate over the Iran strikes, with other GOP figures publicly defending the administration's strategy and predicting benefits such as falling oil and petrol prices.
