Posing a slightly different variant of the question, how does anyone deal with capturing a Japanese city in the WW2 scenario that comes with the game? In that scenario, building settlers is not an option, so I really do not like to raze captured Japanese cities as I need them for stepping stones to get to Japan. I am open to suggestions.
Just keep them and starve them and don't worry about them. They won't culture flip. After the resistance is over I usually rush an airport to get troops to the front.
