> What happens to the incentives of terror groups in response to such a policy?

You're imagining these people to be some sort of loyalists, rather than something closer to anarchists. Triggering military responses is going to be viewed as a bonus.

I'll note people rather frequently claimed Bin Laden wanted the US to be tied up in the military quagmire that their terror attacks produced. There's certainly some logic to that idea. His organization was too small to do much direct damage.
