Re: Fall of empires (and civilization too?)
I think the bigger problem, assuming he does actually lose, is that he's still president for ~3 months(?) Think what damage an angry narcissistic toddler could do in three months with that power.
After that point though, he's not president according to the constitution, and I think the secret service and the military will not take orders from someone who is not president. If militias did take to the streets, I think they'd quickly find that AR-15s are good for shooting up schools of unarmed kids, not so good against the US military.
