Events post September 11 are no war on terrorism. They are a much wider Crusade against Islam and its targets are Muslims. Even a superficial analysis of events confirms this.
It simply cannot be the case that an alliance of some 40 of the most powerful nations with all their wealth, military might, intelligence and propaganda resources have mobilised against one man in a cave with a few hundred followers. Nor is such a force required to defeat a lightly armed militia force such as the Taliban.
