I never understood both sides and their actions. I mean I find both Islamic fundamentalism and American actions all round globe both equally dumb.
I don't think OBL ever had it as an explicit aim to pull down US militarily or culturally transform US into a Islamic state. That is impossible, and I assume somebody like him already understood that. I guess his aim was to drag US into a war and then reduce them to a state USSR, now russia was in 1990 post Afghanistan war. Long wars benefit nobody. They are a huge drain on man power, economy and morale of a nation. Its actually surprising that US fell for it. I was expecting more of a Intelligence based response where the CIA would hunt him down and kill him, instead of wasting trillions dollars.
On the other hand. Afghans seem to be very stubborn people. They don't give up easily no matter how shitty state they are in. Its just in their blood and culture to not accept foreign occupation over them. Even the British that had the entire Indian subcontinent under them couldn't conquer them. In the recent history alone, every body knows what has happened of USSR after going there. So no matter how bad the Taliban is, they still consider them as their own country men compared to Americans who actually released them from their bondage.
As a moderate muslim, I feel bad every time I'm pulled up for an ideology which I have nothing to do with. I've been a subject of religious discrimination many times since 911. I've been asked to come for extra rounds for job interviews, pulled up separately and checked at building security points, had troubles to open bank accounts, asked to delay visa filing for visiting abroad etc innumerable number of times. I feel having an arabicized name a huge liability to carry, a kind of burden for which you have to pay no matter even if you have nothing to do with their ideology.
On the other hand I see so much turmoil in the west, due to the war ordinary people like me having to pay for no mistake of theirs. Wars, economics crisis etc.
When I look at all this, I can't help but wonder that perpetrators of these crimes actually won.
