I mean, I know the US burned a lot of international goodwill invading a country (Iraq) that was completely un-involved with the attack on false pretenses (weapons of mass destruction) while ignoring the mastermind (bin Laden) for a decade, all the while more-or-less flaunting an illegal off-shore prison where hundreds of people, some of whom were definitely innocent and many of whom weren't particularly guilty, in inhuman conditions, but try to remember what things were like immediately after the attacks.
Back in 2001-2003, America was still the good guys, and we'd just had two 100-story skyscrapers in our largest city destroyed in a morning, with thousands of people killed. Hell, at the time we thought it was tens of thousands. Other countries - Sweden and Italy and everyone else - weren't bending over backwards to help us extraordinarily rend people because the CIA has magic powers and can do anything they want, anywhere they want. They were complying because, well, shit, 9/11.
You could very well argue that Bin Laden won, especially because I highly doubt a guy like Trump would be able to win the presidency if 9/11 never happened and Trump is doing more damage to the United States' interests at home and abroad than the last 6 presidents combined.
All that's still missing is a war.
