Yeah, I wish the AI operated under the same rules as we do. I've even "choked" the very last enemy Civ City left, by: moving armies onto all it's resource squares, blocking it's sea squares with Battleships and then building my own Civ right by them and overtaking all their resource squares (can't culture flip a capitol city) through culture.
They still produced armies, even with all their resources cut off. I also sent in spy ring after spy ring, until I destroyed every building and stole all their money -- and yeah, I even kept disrupting their rifleman production -- all to no avail.
