Us: 4.5 billion
Them: 1.5 billion
Us: Modern Weapons
Them: Terrorism

Can you figure out a realist scenario where they win? I don't want or expect it to come down to us against them but under any circumstances we win and modernity survives. If it is about money we win. If it is about justice we win.

There are some unlikely possibilities thet would be grim but we still win, unless you think they really will benefit from Allah's intervention.

The events of 911 are disturbing and tragic in a way that we have not experienced in the past but overall this situation is nothing compared to the cold war and the very real threat of nuclear holocaust.
