2003年10月，时任美国国防部长拉姆斯菲尔德曾提出一个问题，至今仍很中肯 ： “ 我们每天俘虏、击毙、关押和改造过来的恐怖分子，能比伊斯兰学校和激进宗教人士每天招募、训练和派遣出来反对我们的人数多吗？
The question raised in October 2003 by then US Secretary of Defense Donald Rumsfeld is no less relevant today: “Are we capturing, killing, or deterring and dissuading more terrorists every day than the madrassas and the radical clerics are recruiting, training, and deploying against us?”
