Quote from Lucrum:
Whether you agree or not many including some in the military consider Obama and our bloated, intrusive, run away federal government to be the internal threat.
That's going to be a real dilemma for military personnel some day. Uphold their oath, or fire on their own friends and families.
No way to know for sure but I think it would play out much as it did in the USSR. Most soldiers refused to fire on their own civilians.
