Brutalised young adults do brutal things. Doesn't matter if they're American, British, Iraqui or Icelandic, Christian, Muslim or Hindu. Most involved will likely be banal in their ordinariness. There is no clean war. This happened before violent video games, this is the side of human nature we most need to guard against.
The fact it happened is nothing to do with America or Americans. The fact the circumstances that allowed it to happen came about are to a large extent the responsibility of the US government.
The American government have been grossly incompetent and deceptive in their conduct relating to Iraq. The British government have been USass lickers. 'Quis custodiet ipsos custodiet', or rather 'Quis custodiet ipsos Americanii'.
How can America have any credibility as a just and fair world power and expect other countries to trust it (as a political entity, you'all Americans in general are just fine and friendly people)?
It is very very sad. America has such potential for good, but they can equally totally screw the pooch.
And yes, it's jolly unfair that America always gets criticised. But which part of it being the most powerful economic and millitarilyy active country in the world don't you get? There's so much more to criticise on account of scale; it's not that Iceland doesn't do bad things, it's just they're tiny.
