Blocked interstates leading into the cities will starve them out.
A siege is easy by stacking up miles of 18 wheelers going into the cities
“Leftists and non-Leftists are going to be all intermingled, and THAT is a problem.”
The closest parallel is probably the Spanish Civil War.
Why is that a problem?
