Obama's Iraq Logic

All be it I don't agree with Obama on the issues, I do think he is a very articulate, intelligent person. That is why I was somewhat surprised when I read this in AP News:

Democratic presidential hopeful Barack Obama said Thursday the United States cannot use its military to solve humanitarian problems and that preventing a potential genocide in Iraq isn't a good enough reason to keep U.S. forces there.

"Well, look, if that's the criteria by which we are making decisions on the deployment of U.S. forces, then by that argument you would have 300,000 troops in the Congo right now — where millions have been slaughtered as a consequence
of ethnic strife — which we haven't done," Obama said in an interview with The Associated Press.

"We would be deploying unilaterally and occupying the Sudan, which we haven't done. Those of us who care about Darfur don't think it would be a good idea," he said.

What Obama did was commit the Tu Quoque fallacy. When confronted with possibility of genocide in Iraq, Obama turns the focus to the uninhibited ethnic strife in the Congo as if it where justification to the outcome of his plan. Here is the simplified version of the argument that Obama is making to help point out the fallacy:

American: If the US pulls out troops in Iraq then ethnic strife and cleansing will occur.
Obama: Yes, but the status quo allows for genocide in the Congo.

See how the argument does not make sense, it doesn't address the issue. In other words, when people claim "Obama's plan will cause genocide", Obama responds "you already allow for genocide." That's not a suitable answer.
