While we recognize that it was a big deal for you, and certainly an important event because of the fallout that it caused. The rest of the world does not remember 911. What I mean, is, the rest of the world has a lot of empathy for what was something really meek actually (Not saying that thousands of people dying is little, but it shocks Americans all the more because they are not accustomed to fighting or being attacked at home) but does not consider it a big deal by itself. Same thing with Bin Laden, even more so, perhaps. The fact that a world power with millions of military budget and who's constantly assassinating foreign figures and constantly at war, managed to make a hit on a target, it's not all that incredible. It's not like we think it isn't an achievement, it's just not something that we consider big. Like when you were in university and a friend of yours managed to buy a really sweet car. Good for you, nice car, I won't remember it a week from now.
