Couple of issues after boning up on the topic
This is a spontaneous, popular uprising. Unplanned and uncoordinated. Those usually work about as well as it did in Hong Kong. I don't know when people are ever going to figure out you have to meet force with superior force. They aren't going to talk their government into doing the right thing and/or abdicating power.
The World could cut off ALL support for the Cuban government and China will step right in just as the Soviet Union did 60 years ago. I mention that because I saw that idea, among others, bandied about by armchair know-it-alls.
I tend to agree with whichever egghead stated that many of the Cuban people would turn and support the Cuban government against direct, US military intervention. I've stated the same every time someone has come up with direct US intervention in Iran. Most Cubans are going to STILL blame us for most of their woes.
The problem is there is no "leader", nor organization of any kind to deal with. If there was, I'd say just start dropping supplies in an area the resistance has secured. Establish communications with them and see what they need.
I'm all for giving the people internet to keep laying it on the web hot and heavy, but it is not a means of communication to be used by an organized resistance. It's an unsecure means of communications the enemy has as much access to as the resistance.
While all this is happening in real time, we have a bunch of talking idiots, having meetings, weighing in on the topic like they know something (most don't even have a clue what the embargo is or means)such as BLM, the idiot occupying the WH, and every pundit with a keyboard and media access.
I wouldn't want help from the US. Every time we "help" the bad guys win.
