President George W. Bush on Monday sought to dampen speculation about a US military strike on Iran as the Islamic republic's hard-line president softened his tone, saying he wants dialogue rather than confrontation. Bush, in an interview at the White House with C-SPAN, dismissed talk of a US military strike on Iran as political chatter. He also said there is still a chance to resolve, through diplomacy, the standoff over Tehran's nuclear ambitions. Still, Bush called Tehran a "belligerent" regime with nuclear ambitions that will lead Iranians into isolation. "The Iranian people are good, honest, decent people and they've got a government that is belligerent, loud, noisy, threatening - a government which is in defiance of the rest of the world and says `We want a nuclear weapon,"' Bush said. "So our objective is to keep the pressure so rational folks will show up and say it's not worth the isolation."
