It's not a military junta. The President has a judicial, not a military background.
McCain on the other hand clearly wants the Muslim Brotherhood back in power. FYI the Muslim Brotherhood are now spreading propaganda accusing the current President of beinga Jew. What a charming bunch.
So if there were massive Tea Party anti-Obama demonstrations in DC, then the Secretary Chuck Hagel along with the Joint Chiefs of Staff orders to military to remove Obama from office and in his place puts in Chief Justice John Roberts as interim President until elections which will take place at some unspecified date, you will consider it not a military junta.
