Inobu, Colin Powell has made statements that they will act in the manner you suggested, cutting off the cash. I agree whole heartedly. I hope it goes a long way to silencing the guns, sooner.

A serious question to those who think killing the monsters is not the answer. How many years until your turning the other cheek leads to the Bin Ladens of the world seeing the error of their ways? How many deaths will it take till THEY know too many people have died? Be Honest.
If you seriously believe they will learn their lesson in a generation or 3, Is it a service to humanity to permit the learning experience?
in the mean time, Will the hate spread like fungus on the lakes of tears? Will their methods become the "norm"?
Would you have employed pacifism against Hitler? Would it have worked?
Like I said earlier , it is Pseudo-pacifism. Very Occasionally the Humane thing to do is FIGHT. This is one of those times.
