"I, _____, do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God." (Title 10, US Code; Act of 5 May 1960 replacing the wording first adopted in 1789, with amendment effective 5 October 1962).
Remember those words? Have you actually thought about those words since you spoke them?
How about this fact:
A military order must have a military connection and must not contravene existing law, such as the Constitution, treaties, and statutes.
Now, here is the rub, if, as it is now, the President of the United States is or has directed government agencies to engage in activities that directly violate the US Constitution, and the Bill of Rights, are the personnel of the United States Military legally required to continue to follow those orders?
Finally, the international community and the world court WILL hold military personnel accountable for war crimes that are committed within the homeland of those military forces.
Something to think about....
