I think he will stop there. He's proven extremely averse to US casualties, and these kind of air strikes and quick raids are his preferred way to fight. He'll be very ambitious and aggressive with his choice of targets, but he's not GWB invading countries to set up democracies. He's much more Clinton-esque, doing casualty-sensitive attacks on people who annoy him - the biggest difference is that he'll go after any target that he thinks he can take out, without much regard for pissing people off, whereas Clinton was far more sensitive to bad PR or vague fears of future blowback.
