Elections 08 - Could another war change public opinion?

[boracay]

Let's speculate:
Both Obama and Clinton are weak in case of war vs any republican candidate.
Let's say public opinion in early spring 2008 is 55% for democrat candidate and 45% for republican candidate (sorry all libertarians here).
Dems demand soldiers home from Iraq, reps would keep them there.
Any probable situation in Iraq wouldn't turn public opinion at home.

How likely would it be that Israelis suddenly attack Syria or Iran?

It would be in their interest.
It would be in the interest of the current US administration.
But of course they would never do it without getting a green light for action from Washington before.

Could this turn public opinion at home?
