You want agressive? How about we go WW2 and carpet bomb the entire country with a 5000 mile wide 2000 mile long flock of heavy bombers? That would be aggressive enough and we wouldn't need to waste a whole lot of money on training people or deploying them. Plus no one gets truamatized by a war except for anyone hiding out in the countryside that just got obliterated.

Also we could use more efficient ways of stopping Osama. The Japanese called them assassins...I call them the Well Oil'd Killin' Machines.
