President Bush is more likely to attack Iran if he thinks Senator Barack Obama may be elected, Weekly Standard editor Bill Kristol told FOX News Sunday morning.

Kristol added that if Senator John McCain was going to win the presidency, Bush would "think it more appropriate" to let him deal with the issue.

Senators McCain and Obama have often sparred about whether military force or diplomacy should be the primary way of dealing with Iran, according to an article by the Los Angeles Times.

McCain has criticized Obama for his willingness to meet with Iranian president Mahmoud Ahmadinejad, but a Gallup poll shows 59 percent of Americans support a meeting with the leader, the Los Angeles Times reported.

Bush said that McCain is "not going to change when it comes to taking on the enemy" when he declared his support for the candidate at a White House press conference in March.

WALLACE: So, you're suggesting that he might in fact, if Obama's going to win the election, either before or after the election, launch a military strike?

KRISTOL: I don't know. I mean, I think he would worry about it. On the other hand, you can't - it's hard to make foreign policy based on guesses of election results. I think Israel is worried though. I mean, what is, what signal goes to Ahmadinejad if Obama wins on a platform of unconditional negotiations and with an obvious reluctance to even talk about using military force.
