Bush is an easy scapegoat, he's already going down in history as one of the worst presidents the US has ever had, he probably deserves worse than that but the world is full of privileged, wealthy, powerful men who are morally corrupt, and there are many worse than him.
There are plenty of worse presidents (Andrew Johnson) and even more morally corrupt ones (Andrew Jackson for example, or even Richard Nixon).
If you want to evaluate the presidential performance, you have to understand the history of the United States and his predecessors. Also, you have to take into account what information he had at the time of making a decision, right or wrong.
It's easy to play the blame game, its hard to do your homework and understand another's point of view. Making a blog with an irate name is one thing, making a blog with facts, figures, supporting evidence, discussion points, and alternate views is completely another.
