Today is the 6th anniversary of the September 11, 2001 attacks. Most people consider it to be an American tragedy just because it happened in the US. But the fact is, dozens of nations lost citizens in the attacks. It happened in America, but not everyone who died was an American citizen.
According to this page from the United Arab Emirates' American embassy, the victims of 9/11 came from 82 countries; including 25 people from Canada, 67 from Britain, 16 from Jamaica, and 15 people each from the Philippines and Mexico.
When most people think of Americans, they think of White people who speak English. But the people who died in 9/11--an event that happened in America--are so much more diverse than that. They came from more than 80 countries in 6 continents. The French newspaper Le Monde said it best with their September 13, 2001 headline: "Nous sommes tous Americains" ("We are all Americans"). It seems like the only thing that's really "American" about 9/11 is its location. If we're talking about the deaths and the loss of human life, 9/11 was more global than anything.
And even if we do consider only the American citizens who died, we still get a racially mixed group of people; most of the victims were from New York City, which is one of the most ethnically diverse cities in the world.
