Just to be statistically fair -- we deployed 4 million troops during WWII. Perhaps you should speak of percentages rather than numbers.
Our force in Iraq is now, and has always been, tiny, tiny, too tiny -- IMHO.
That is what the surge is ultimately doomed.
All we can hope at the moment is to buy enough time for the Iraqi Government to take charge against terrorists without heavy American presence.
Comparing Iraq with WWII is ridiculous.
The Iraq war is more like the war in the Philippines where 126,000 US troops fought and 4,324 died between 1902 and 1913
