and if you want a rebuttal, troop maneuver isn't like fucking hoi4 where it can be almost instant for your forces to entirely encapsulate land (victorypoints). that same logic would apply to americans. naval transport is slow, it would take a long time for us troops to beachhead in cuba and in that same time the soviets would beach head and supply the opposite side.  or if anything, if they couldn't feasibly do that, they would just send nukes at american cities and it would be the mad we all wanted to prevent. like i'm sorry what you're defending and asking me to reply to is dumb. it's a video game type of explanation of conquest and occupation. it also assumes that the cuban people wouldn't form an insurgency and fuck us insanely so. they were united as a people for the most part, it was possible.
