The one explanation that is excluded is that America’s wars in Muslim lands overseas are radicalizing Muslims at home. Never mind that the homegrown Muslim terrorists who attacked the London transport system in 2005, and the various Muslim plotters who have been caught in other Western countries before their plans came to fruition, have almost all blamed the Western invasions of Muslim countries for radicalizing them. Never mind, above all, that what really radicalized them was the fact that those invasions made no sense in terms of Western security."
