this mf thinks we still have medieval walled cities, like dude, you can literally just... walk out of the city. I mean, yeah, you can indeed disrupt logistics, but there's a pretty big gap between "trucks can't get in to deliver supplies" and "entire population is trapped inside of the city". Also railway transport isn't real I guess

I guess city folk don't have any construction equipment of their own to clear and repair their roads. Also I guess the roads are just going to be conveniently completely empty for however many hours it takes you to block them, because, uh...
do an area study 
In the Civil War, both the Union and the Confederacy went out into rural areas and easily crushed all resistance to the regimes in Washington and Richmond. It happened so quickly that barely any history book talks about it.
If a Civil War breaks out in the modern US the same shit would happen because the real conflict would be Texas and California fighting over the remaining drinking water.
