You F with our country, not only will we track you, personally, down and kill your worthless butt, and as many of your equally worthless kin as that mission takes, but your entire country and/or those that supported you will simply cease to exist.
Afghanistan should have been fragmented along ethnic lines into mutually warring pissant regions, and the same fate should have befallen Iraq.
Turkey, who wouldn't allow us to stage on their turf would be rewarded with a hostile Kurdistan on their border...
I do agree. Specific details of implementation are always debatable, but I generally think that a terrorist attack on an American citizen should result in a devastating attack on an Islamic population center with the goal of killing a lot of people. And always mention that Mecca could be a target too.
Trade the attacks back and forth. See who decides to stop attacking first.
Terrorism is best fought with terrorism. Make the other side afraid to attack you.
