Sen. John Kerry -- chairman of the Senate Foreign Relations Committee -- in a Washington Post op-ed criticized Mitt Romney's foreign policy approach to Iran. "I join this debate because the nuclear issue with Iran is deadly serious business," Kerry writes. "It should invite sobriety and thoughtfulness, not sloganeering and sound bites. The stakes are far too high for it to become just another applause line on the stump. Idle talk of war only helps Iran by spooking the tight oil market and increasing the price of the Iranian crude that pays for its nuclear program."
President Obama in a news conference on Tuesday criticized the GOP candidates' loose talk of war with Iran, this the situation is "not a game."
