They'd probably a bit more proactive, and it might be easier for Marti to build up support for the Rebels in places like New York, especially if the CSA gets involved in a bad-blood scenario.
Without the Keys, though, it'd be hard to stage any serious operations, as there's no good jumping off point, as everything would have to be sent down the coast.
IDK. It depends. I'd put money on it being simply named Dominica or Hispaniola or something.
Thanks for the input but whose Marti, and bad blood with who exactly? Also I've read other posts about the possibility of the CSA holding onto the keys and I agree with those who say that such chances where slim. So I'd say that it might be easy for the USA to have naval bases there to launch off of towards Cuba. I'm not an expert though so there could be possibilities that would change that.
