Wait a cotton picking minute! The Constitution is something I took an oath to when I was inducted into the US Marine Corp. The military has no oath or allegiance to a particular president. Obama is unable to have a litmmus test - will fire on American Citizens as part of any oath or allegiance to him. This would be a high crime making him eligible for Impeachment. Not like he is not already eligible for impeachment. Opps I forgot we have to many ball less politicians in DC.
I do solemnly swear that I will support and defend the Constitution of the United States against all enemies, foreign and domestic
So begins the Oath of Enlistment for the U.S. military, but in an explosive interview with a National Guard whistleblower shown below, soldiers are now being advised they will be ordered to break that oath should civil unrest erupt across the country.
On another note; I wouldn't count on lots of rational consideration or compassion from anyone facing me with a weapon in his or her hands and orders to make sure I behave myself.
The great consideration is that any potential confrontation will likely be between the common folks and either reservists or the NG, both of which are likely to be innured to combat while trying to remain sane while existing in-between those common folk and the standing military. In that instance you have to weigh "citizen soldier" against "guy with a weapon and orders from recognized authority".
Your opinions will not determine the other guy's actions.
