For me the day is inextricably linked to my homeland, Moscow, Ibiza, family...
I had moved to Moscow 2 weeks before, but immediately took off on my first trip to Ibiza. I came back to Moscow, just started to settle in and then this happened a couple days later.
I saw the first report on Russian television but had to run out to pick up my local registration document. I remember standing just outside the gates of Red Sq trying to get my brother in NYC on the phone. How ironic... at the gates of what we once called the "Evil Empire", but it wasn't these guys that attacked us but some new shared enemy.
Didn't have cable TV installed yet so no English channels. No Internet at home either. Decided to head to an Internet cafe in the shopping mall next to the Kremlin and spent hours reading the blow-by-blow. Then I joined a friend of mine who was in town on business (together with a Bush administration official) at a local hotel to watch CNN.
With my brother in NYC and my parents in the Washington, DC area, it was a quite a shock.
But what angers me almost as much as the attack is how it was subsequently used to justify the abuses of power of the Bush administration, domestically and internationally.
And on a more personal level, it was so hard visiting the States for the few years. People were so different. Everything was Before 9/11 and After 9/11. People insisting on blind patriotism and waving flags without even trying to understand the geopolitical forces at work.
If there's an upside, it's that many more Americans take notice of what's going on outside our borders now. At least, they know where Afghanistan is, they've heard the name Kyrgyzstan on the news, they might even know that Georgia is a foreign country in addition to being a state.
As an aside, I can't believe I've been living in Moscow for 7 years already!
