What Karnak said. Capitalism in America isn't dictated by the administration, so crediting one administration or blaming another in such a sweeping fashion is very inaccurate.
Now, you might have an admin call for change in the operation, call for investigation, etc., but they cannot directly force the economy one way or another...
...now you might argue Bush is scaring everyone with talk of war, but then again, we didn't attack ourselves on 9/11. There will be more attacks, and the time has come to get proactive. War may be scary to business, but so is having our major cities attacked. If it is a choice between the two, I choose proactive war, economy be damned.
