Allies Resisting as U.S. Pushes Terror Label for Hezbollah

This makes sense to me. Since Lebanon is in such disarray after the assasination, probably aided by Hezbollah, at least not resisted by them, we ought not push them. This is like not giving the bully on the playground detention because he just beat up a kid and you don't want to make him mad right now. So, if Hezbollah settles down and "joins the mainstream political process" then we act to designate them as terrorists? I don't get it.
