What would the US do if Iran closed off oil supplies from the Gulf? Strangely enough the president didn't respond to the question even though it is his responsibility. Neither did the Secretary of State. The administration left it to the Pentagon to respons with "yada yada not tolerate yada yada" but the Pentagon doesn't get to say what the US will or will not tolerate. A female Lt. spokesperson for the 5th fleet claimed "the US is ready to counter malevolent actions". Well duh. My guess is that Barry and the radical greenies would like nothing better than closing off oil to the US.
