Anti-war, Anti-goverment albums were all the rage in the early 2000s, once the aftermath of 9/11 had a few years to wear off. Green Day with American Idiot, Pearl Jam with their "Bushleaguer" song, Bright Eyes "When the President Talks to God", hell the Beastie Boys even had an anti-GeorgeW song "In a World Gone Mad". That shit was big circa 2002-2004 or so.
That being said, I compare Green Days "American Idiot" to U2s album "All That You Can't Leave Behind" from 2000. Both albums were good compared to some of the crap the bands had done just previous to that, it brought them back out of a decline briefly, but neither album was anywhere close to the bands at their creative peak (Green Day in the early to mid 90s with Kerplunk-Dookie-Insomniac, and U2 circa 1980-1990, ending with Achtung Baby, their last great album(maybe their best)
