If you haven't listened to the full length, then you should. Same material as some songs on Within Death.... but much more developed and "mature" sounding. Really a great album, maybe a bit too long, but overall a very very solid album.
I have to laugh at this whole Nationalism thing. American Nationalism, really? I can understand European Nationalism, or any other culture/nation that's existed for a long time, but c'mon American Nationalism is a joke. What proud culture and tradition in American history needs to be preserved? The melting-pot culture we have, which is a combination of every damn culture in the world? Also, when you take into account the array of wildly differing regions and attitudes within the US, the idea of a comprehensive American Nationalism is absurd. The only thing that unites Joe in Seattle to Jim Bob in South Carolina is the fucking brand of deodorant they buy and the TV shows they watch. THAT is our glorious culture.
For the most part, I think people touting American Nationalism are really just confused Europhiles, and also people who want to feel a part of something greater than they are (which also can be said of religion, political parties, etc...). The only American Nationalism I would accept would be from Native Americans.
BTW, I'm an American.
