Honestly it would be nice if things were that simple, if the eastern bloc were only funneling weapons into their allies, but nope they're shipping guns and bombs into every nation they can in an attempt to install autocratic loyalists across the Middle East, Asia, South America, and I expect Africa soon.
That's the real problem is they're already waging war on the west.
Weathering the storm is different from working towards good relations with the US. Cuba has extended numerous olive branches, and at some point, we have to accept that it’s not Cuba which needs to change course with regards to US-Cuban relations.
And there have been high points and low points in the US-Cuban relationship which has recently worsened as USA tightened the Embargo under the 2nd Trump admin and now the Cubans are literally in the news article that comment is under cheering for literal War with the USA as the Castro family declares they are ready and willing to fight.
And all I'm saying is:
They don't need to have a war. They don't need to be fighting for the Chinese, for the Russians, the fucking Iranians for goodness sake. Cuba could just give trump a proverbial handy by agreeing not to militarize and help USA secure the surrounding waters, trade would return, and wait for the demented old fuck to fall asleep and forget about them. In a couple of years it would all return to as if nothing had happened.
