Is that data supposed to go back before 1990? Because it doesn't on my end, and as such that data isn't going to prove your point or disprove mine.

North Korea is confounded by the fact that Western sanctions are in large part responsible for famine: the region is notorious for not being very arable, and the USA's meddling with the South Korean puppet state actively worsens the situation. Similarly in Cuba: not every fault can be blamed on the USA, but if you don't think the continuous trade embargos aren't partially at fault for the situation, I don't think you're honestly evaluating the situation.

Cuba may have free education and healthcare but it’s shit compared to any western European country

Don't let perfect be the enemy of good. I would much rather have access to any sort of free healthcare than not have access to any, as is my current lot in life. I don't care how good certain exclusive healthcare is, when the majority of the population has no access to healthcare. But frankly I think you have an unjustly negative view of the Cuban healthcare system:

Quoting Ileana Morales from the Cuban Ministry of Public Health,

Cuba has the highest ratio of doctors per inhabitant in the world. We have more than 100,000 doctors for a population of 11 million – 9.2 for every 1,000 inhabitants. We also have the highest ratio of health workers per inhabitant – 500,000 overall. But it’s not that we have leftover professionals. We don’t have so many doctors because we like training them, but because we have a health policy that employs all of them. This includes those who are in management positions and those who are committed to our international solidarity missions, our collaboration in health.

... and Cuba doesn't hoard its medical professionals ...

We do a lot of international collaboration. Cuba has been there to support others during all the major health disasters. During the Ebola crisis, Cuba was one of the very few countries that sent medical brigades in Africa. We are always present during earthquakes, fires, and floods. And we always favor communities where most of the time there are no health workers, or we go to places that lack healthcare services. This is the vision of Cuban medical collaboration, which is implemented through two main channels: health workers’ training and provision of care.

Notice that healthcare works differently when it isn't purely profit driven. It works differently when incentive structures favor patient health over profit.

I mentioned this later in my comment: if you look at the suffering caused externally by capitalism, it's at best a wash with the benfits caused internally by it. You're also pointing to examples where things aren't great because of USA's interference. It's disingenuous.

The USA loves to wage economic and ideological war and, when it makes some progress in tearing down its target, point to the downfall of the target and pretend that the downfall is purely due to internal conflict. And you're buying in to that narrative.

The latter part of my comment was, in my opinion, more important than the first part. The proportion of the world's population being hurt by capitalism, compared to the proportion of the world's population helped by it, is massive; the fact that you're putting more value on small benefits conferred to a small proportion of the population at the expense of the rest is unfortunate but to be expected in a defense of capitalism.
