The Carter Foreign Policy Doctrine: Because access to middle east oil is a vital American interest, any attempt to interrupt the flow will be viewed as a hostile act against the US and no response, including military, is off the table to preserve that access.
The Reagan Foreign Policy Doctrine: The US will support financially and possibly militarily, any rebel group or government that resists the spread of communism by Russia.
The Bush Foreign Policy Doctrine: Given that virtually all terrorism is directed toward the US, the US reserves the right to pursue terrorists where they live and train in any country we find them.
Whether you liked any of these Presidents or not, each had a serious, valid foreign policy doctrine for which their administrations would be historically known.
The Obama Foreign Policy Doctrine: All nations with whom the US has diplomatic and economic relations should tax and regulate their industries to combat climate change.
This is what you get when you elect an inexperienced, two-bit community organizer, without a single accomplishment that qualifies him for public office, to the presidency. You get a world-wide embarrassment.
