1. You said "Invasions" was one reason. Osama cited an example of being protected from invasion as a reason for 9-11. You don't see any relevance between those two statements?
2. You did lump them together.
3. Standing on "proper channels" with an enraged superpower was a choice. It would have been a far better choice for everyone involved to hand him over. Do you doubt that Osama was behind 9-11?
1) No, I don't seem much relevance in your statements. The Middle East has suffered a lot from the West. Many Arabs hate the West because of historical things.
2) You want to get pedantic or you want to debate?
3) Do I doubt it? Doesn't matter does it? Would it have been a better choice for the Taliban? Seriously? I doubt it. I mean, they've been getting their fight, they kicked the US out, they're coming back again. Just watch them creep up on Kabul.
