I may disagree with the Commander in Chief and his recent pick to the Supreme Court on what the Constitution means but that is a far cry from being a domestic enemy of the Constitution.

While you are correct that yes the oath of enlistment does require me to "Support and defend the Constitution of the United States against all enemies both foreign and domestic, " before it it requires me to "Obey the orders of the President of the United States," you are flat out wrong on your assumption that Obama has violated the Constitution to the point that a military coup is in order.

If a President ever decided to proclaim themselves President for Life, arrested the House of Representatives and the US Senate, or tried to get rid of the 9 justices on the Supreme Court maybe the oath would require the military to march on DC but a simple disagreement on what the Constitution means is no such reason and quite frankly I would smoke any Soldier in my section who said it did. Under your theory we should have had a military coup every few years as ever since the Constitution was written people have been in disagreement over what it means (IE Federalists V. Anti Federalists, and strict interpritation V. a living breathing document) A military coup is an event that is to serious to joke about and, as for myself I will be saddened if the day ever came the US military had to conduct one.

If you do not like the current President you get your chance in 2012 to get rid of him at the ballot box. You should not want the Army rolling in to DC with Abrams Tanks to do that. In 99.9999% of all cases such talk is about as Un-American as you can get.
