re: Aid to help trapped Iraqis would be a political slam dunk for Obama.

A solid, consistent effort on the part of the United States to aid the Kurds and, as impartially as possible, mediate in Israel and Gaza (which they seem to be doing fairly well) will give him a solid bump in approval. Add to that that the pull out in Afghanistan is only getting closer and that domestic issues aren't really in the news right now and his approval numbers could fairly quickly jump back to around 44-46%.
