comparison with WWII
the Germans attempted to set up a guerilla organization to harrass the Allies after they'd lost - apparently it was a bit of a joke at best. I think the Germans had had enough by then you know? We'd been bombing the shit out of them for years, the whole country was shattered. I guess having nukes dropped on your country also makes you a bit war-weary. The Japanese obviously had suicide bombers towards the end of the war, but when the emperor surrendered, that was it.
so the main difference are that Iraq had a short, sharp war with fairly low civilian casualties (for a war, that is), and there's also the religious dimension.
back on topic again 
of course there's good stuff happening in Iraq, at least the poor civvies don't get mustard gassed much these days. on the other hand, a good end doesn't justify bad means - i.e. just cos it's an improvement doesn't
necessarily mean the war was a "good thing" or conducted for "good" reasons.
