We get lessons from films like this-

Rating: Null/10 (28 September 2002)

And the lessons we get generally get swept under the rug. The film gives us some idea of what happens in urban combat, when ANYTHING can go wrong at ANY time, and how what looked like a simple procedure in planning can wind-up as a bloody mess. I'm reminded of Operation Market-Garden in WWII, one of the biggest blunders in war history, which was entirely preventable (and which made it to the screen in the excellent film, "A Bridge Too Far."} Before we get involved in any more "policeman of the world" scenarios, we ought to think about this.
As to the comments about the massacre of the Somalis, I am neither ashamed or afraid to admit that upon seeing the news photo in 1993 of the American soldier's naked corpse being brutalized by that mob in the streets of Mogadishu, a hatred arose in me for the Somalis which has not abated completely. Prejudice? Sure. I care nothing for them and am only distressed at how so many have flooded our cities as "refugees." But that appears to be inevitable when you play Santa Claus to the world.
