So you think Brzezniski should have fully foreseen that 20 years later Afghanistan would be taken over by a group of low rent, semi-literate Pakistani religious nuts who were financed by a complete mad man from Saudi Arabia with $300 Million at his disposal who became totally obsessed when US troops stepped on Saudi soil?
No, but it does put to lie the idea that American muddling and empire-building does not have consequences. Even 20 years later. That perhaps there was motivation beyond "they hate us because we are so noble and good and have such good fast food restaurants" that most Americans seem to feel so smug and snug believing.
