Whether you believe Cuba is an asshole or not doesn't give the US Empire the right to force the rest of the world not to establish normal political and economic relations with Cuba.
The rest of the world is free to side with the commie assholes in Cuba. No one is forced.
OK, so if that's the case, then why continue with hostilities? Why are capitalists so triggered and scared of communism, if it amounts to nothing?
Kicking you assholes when you're down is hilarious!
Why did the US, UK, France, and 10 other countries invade Soviet Russia immediately after WW1?
Because commie assholes suck.
Why did they spend the 1920s and 30s, trying their best to sabotage and undermine Soviet Russian society?
See above.
Why did four million Nazis invade Soviet Russia
I'll never understand why Stalin's best buddy, Hitler, turned against him.
how, after losing much of its national infrastructure and 28 million people in WW2, did the Soviet Union rebuild and become a nuclear superpower rivaling the United States?
Kill and enslave enough people, you can make some decent, temporary progress.
How and why did the USSR have the second-largest economy in the world by 1970?
Because commies lie about the numbers.
Communism is the most effective and resilient economic system in the world,
Until capitalists stop trading with it, then it's the most delicate
Cuba, despite its economic problems, is an example of how capable socialism is in keeping a nation alive,
They were alive before communism turned them into an economic basket case.
Get out of the way, and let Cuba develop. Stop imposing economic embargoes that force the world not to normalize relations with Cuba.
Sure, as soon as the commies take their boots off the neck of the Cuban people and have some free and fair elections, we'll take our boots out of their commie asses.
I'll let the people I'm writing to decide that.
Decide that you ran away with your little red tail between your legs?
