Yea the terrorists are going to find ways into our country or could coordinate through the internet. Look we can't secure our borders entirely unless you are suggesting we put up a shield and get the Jedi Knights to protect us.
The best we can do is stop giving them a reason to fly planes into our buildings. Every bomb we drop, every country we invade, just brings more people into Al-Qaeda's ranks. Osama bin Laden's whole plan was to get us to invade Iraq and Afghanistan, for that very reason.
Yeah, we should cave on any and everything they ask for. These irrational halfwits couldn't possibly find something else to be suicidal about.
