Reply #5: There is no historical basis for Iraq to exist,

[Sen. Walter Sobchak]

Some foreign dudes with a ruler created Iraq, a nation with no strong national identity and basically zero national sense of loyalty.
No matter what the end game in Iraq is, there is going to be civil war and there is going to be genocide on a massive scale as the goal is going to be the extermination of the Sunni's. That is a given but more blood would be spilt trying to keep Iraq whole against the cultural and religious inertia of the region.

There is no good end to the war in Iraq, there are however some ends that will kill fewer Americans. Preserving the political geography of Iraq isn't worth a single life, American or Iraqi.
