Iran’s top leader issued a new warning Thursday over how Tehran would react to a United States attack. Ayatollah Ali Khamenei’s comments were read over Iranian television.

Ayatollah Ali Khamenei: “The enemies know well that any aggression will lead to a reaction from all sides in the Iranian nation on the aggressors and their interests around the world, and we believe that no one will make that unwise and wrong move to endanger their country and interests, but some say that the U.S. president is not the type who acts based on calculations and thinks about the consequences of his action.”

The warning came as Iran finished two days of war games, including a successful test of land-to-sea missiles. Defense Secretary Robert Gates downplayed the new developments.

Defense Secretary Robert Gates: “My impression is that they make threats like this from time to time. We have no intention of attacking Iran. The president said that; the secretary of state, I said it before. Obviously when it comes to things like these tests, we watch them closely, and other than that I think it is just another day in the Persian Gulf.”
