There's a lot of feeling about this, nobody wants to make a mockery of the people who died, or make less of the fact that America was attacked, but there are also very definite hints that the whole thing has already been made a mockery of by being used to 'fix' things that were never broken, and make broken things worse.
I do sympathise with the American people, but will we have a day for Iraq, a day for Lebanon, a day for Afghanistan, we already have a day for Israel and the terrors of the holocaust, and now we have a day for the US, why shouldn't all countries that suffered losses not deserve a day of remembering?
