That is the basis of my question as a civilian and not knowing.
The oath to defend the Constitution...do most rank and file understand that the Chief Executive/Commander in Chief is subordinate to the Constitution and not a vicar of it always.
Oaths are worthless to liberals, so it will come down to the individual soldier.
But most liberals won't kill for their cause and damn fewer are willing to die for it.
The people like Pelosi, Reid, Obama, Derek Bell, Soros, Warren etc have cultivated a society based on the leaders caring for the people so as to control them. That is the exact opposite of what you need an army to be during time of conflict.
Consider, by way of contrast: The people who are in the combat arms are notorious fitness freaks. They put themselves through grueling, painful exercise rituals for hours a day; long after the army has asked them to perform their duties for the day. Does any liberal icon or large swathe of their population group strike as those sorts of personality types?
Do you see the obese EBT crowds squaring off against us?
Sure they can riot; but then what?
OK, you destroyed the city you live in. Are they moving, en masse, to bivouac in the field for extended periods of time so as to occupy the productive countryside?
Look at the OWS. Field hygene and sanitation was not their strong suit and as a combat medic I'll say a division sized-element can cease to be combat-effective in less than a month due to poor field conditions. In fact, Gulf War 1.0 was the first war in human history where combat casualties actually outnumbered casualties from disease (I've known a doctor who had to debride the socks off of infantrymen). I doubt the liberal horde could carry on a genuine sustained operation.
Hell, I don't even see a real fight. I think we could literally ignore them to death. They're the ones bred for dependency.
