U.S. Defense Secretary Pete Hegseth said Tuesday would be the most intense day yet of U.S. strikes inside Iran. The Islamic Republic, its firepower diminished, vowed to fight on. Israeli Prime Minister Benjamin Netanyahu said the war's aim is a popular overthrow of Iran's government, and "we are breaking their bones." White House press secretary Karoline Leavitt said U.S. President Donald Trump "is not making anything up" as he offers varying justifications for launching the war.
