Correct me if I'm wrong, but I thought the focus of Mustaine's bile on this album was the United Nations, not Bush? United Abominations and all that? And the fact that I read an interview where he talks about being proud to have met the President and shaken his hand? Meh, I don't know.
But yes, I was pretty disappointed as well. Only a few good songs, and they're the ones that were released before the album actually came out.
