If there is a President Obama, will this make Israel feel that it is more "on it's own" militarily and given a more hawkish Israeli government does this mean we're looking at an Israeli strike on Iran within a year if Obama is elected?

I'm not baiting this for internal political purposes, but looking at it from a purely international academic prospective. If Israel feels that the US will not fight its battles or take care of its security needs, will that increase the odds they will act unilaterally?

The follow up is: If they do, is that in our interest?
