Here is an article about one postwar anti-communist resistance fighter that is telling, the last known surviving fighter made it to 1963 in postwar Soviet occupied Poland, and it is noted in the article that for that one fighter, there were 200 known or suspected active supporters.

There is a tipping point in resources and public sentiment where evacuation makes more sense than staying and fighting. Personally, I see establishment of foreign safe havens for non-combatants as a smart thing. A last ditch barn turned command bunker is no place to be with your wife and kids.

A half dozen fighters supported by an expat community that lives in relative safety in my opinion might be a much smarter way to go than having a besieged and starved out community that resembles an early 1900s Indian reservation.
