President Bush is vowing to press Iran to give up its nuclear ambitions, though he's tempering his tough words with talk of diplomacy.
At a campaign town meeting in Annandale, Virginia, he declared, "Iran must abandon her nuclear ambitions." And he said he wants to "keep pressure" on the Iranian government.
But, he stressed that to do so America will deal through its European allies and the UN's nuclear watchdog agency.
In his 2002 State of the Union message, Bush included Tehran in his "Axis of Evil." U.S. officials have long believed the Iranians are secretly trying to build a nuclear bomb.
However, administration officials say they see a new international willingness to confront the Tehran regime.
