'War is God's way of teaching Americans geography," as journalist Ambrose Bierce once put it, and it's true that many denizens of the Empire have little curiosity as to what goes on outside its borders unless they have to bomb it. This attitude was best summed up by the Texas Republican former House Majority Leader Dick Armey, who sneered "I've been to Europe once. I don't have to go again."

Filmmaker and liberal gadfly Michael Moore uses his latest film, "Where To Invade Next," to explore the novel idea of learning from other countries instead of attacking them. He spends his two hours as a one-man army "invading" Europe, Scandinavia and North Africa to claim their best ideas for America.

It's a pretty weak framework on which to build a movie, especially compared to the single-issue focus of earlier Moore docs, such as "Bowling For Columbine" and "Fahrenheit 9/11", but Moore runs with concept for two hours in an ode to Euro social-democracy.
