Dan Senor. the Special Adviser on Foreign Policy to the presumptive Republican nominee, told reporters Sunday morning that Romney talks tough about the potential for war to further the chances of peace.

"As the governor makes clear in his speech, those who argue that talking about military action is irresponsible are actually those who are making a peaceful solution — a peaceful outcome — less likely," Senor said. "Because the governor believes that at this point the only thing that could focus and force the minds of the Iranian leadership on ending their nuclear weapons, their path to a nuclear weapons capability, is the belief that the alternative is far worse."

In remarks in Jerusalem Sunday night, Romney will seek to stand by Israeli officials as they contemplate their options against a regime committed to their destruction. "My message to the people of Israel and the leaders of Iran is one and the same: I will not look away; and neither will my country," Romney is expected to say.

Senor also pledged that Romney would support Israel in the event it undertook a unilateral strike on Iranian nuclear facilities.
