So you're claiming that hatred of Russia had nothing to do with the invasion of Afghanistan and was simply cause they were jealous?
No, but why didn't they keep pushing Russia after the Soviet Union fell apart?
You're expecting rational behaviour from terrorists? You won't get it. Once you hate someone you don't stop just because they stop doing what made you hate them in the first place. That said, one of the major reasons was cause of Chechnya. I wouldn't claim it was the cause so much as a justification for the hatred they already felt. Much the same as US policy on Israel/Palestine is.
On the other hand why would a kid from suburbia run with the Taliban? Of course there is more to it than just jealousy, but that certainly is a factor.
Okay, how is that an example of jealousy? He was jealous of his own freedom? He was jealous of how his county had too much power and decided that it shouldn't?
To me that's an example of a convert taking on the prejudices of the people who converted them. In which case the reason for the hatred stems from the reason why the person converting him had those prejudices.
