Senate Foreign Relations Committee Chairman Jim Risch, Republican of Idaho, said, “This war is Israel’s war, not our war, but Israel is one of our strongest allies and is disarming Iran for the good of the world." Risch added, "This is not the start of a forever war. There will not be American boots on the ground in Iran."

Legal expert John Yoo argues President Donald Trump has constitutional authority to strike Iran on his own volition, while lawmakers debate their role in authorizing military action and declaring war.

Both parties have seen splits in recent days over the prospect of striking Iran. Kentucky Rep. Thomas Massie, a Republican and a longtime opponent of U.S. involvement in foreign wars, posted on X after Trump announced the attacks that “This is not Constitutional.”
