Spain's 9-11

The news is trickling in that the attack in Spain (Spain Struggles to Absorb Worst Terrorist Attack in Its History) was not from the Basque separatists (who don't do this kind of thing) but from Al Queda. It makes sense; remember that Spain was one of the only allies the US had in the War on Iraq.

If it comes out that it was Al Queda, then we are faced with the interesting moral issue of how do we acknowledge another country's "9-11"? Do we hold ours as special and unique or do we say the two are linked and hold it to the same level of sadness and sanctity?
