“The only reason why I might disagree with this is 1) if we truly need PR as a naval/military base or 2) if there’s a real chance that an enemy (China,Russia,Venezuela,Cuba,etc) might succeed in filling the vacuum created by our departure.”
That’s BS. There’s a slew of other Caribbean islands that our enemies could use as bases if they had the desire to. I doubt that an independent PR would want to get on our bad side. And PR kicked our base out of Vieques just a few years ago. We need them like a hole in the head. Give them their freedom.
Last time they voted, the didn't want it, IIRC.
