It's Iran, stupid
This is not a new war. It is the same war. It has waxed hot and cold for decades. The consistent policy implemented by the U.S. government, sometimes through its proxy Israel, is to prevent national economic, social, and democratic development anywhere in the region that is not on U.S. terms. The object, a pillar of U.S. strategic interests, is control -- not literal possession -- of petroleum resources.
That pretty well summarizes it, and I'm afraid the Dems will buy in once again. After all, nobody can resist AIPAC.
