Exactly. What we would LIKE to do is "destroy terrorism", but that's not likely, unless Islam is expunged from the earth, which is even less likely. What we are HOPING to do is convince the terrorists that the US is too hard a target, and attacking it will mean too many of their civilians die. That is to convince them to attack 'softer' targets : The EU (where in certain locales Muslims are 12% or more of the population), Asia (Russia and China have Muslim populations), or best of all, other Muslims. If the radical Muslims and the moderate Muslims (the ones who only want to enslave or 'dhimmize' nonmuslims, not kill them) wind up playing out the Calico Cat and the Patchwork Dog tale of our childhood to its conclusion, so much the better.
