There's a concept where some people can accept a horror story or sci-fi/fantasy story in a real world setting, where the horrific, sci-fi or fantastic element is the only thing that's made up, but they can't tolerate a speculative setting.

There's a sort of contract in the audience member's mind that they only have to accept one fake thing. If the fictitious version of the real life enemy is an exaggeration or caricature of the real thing, you can roll with that and accept the artificial exploits of the made-up heroes. The Soviet Union of Tom Clancy's novels was enough like the real thing that you could accept the incredible plots, like the defection of the men entrusted with the most advance Soviet weapon, or the blackmail of a KGB chief to extract an American agent who is the number 2 man in the defense ministry. It also helped Clancy keep the same cast of Russians when his novels had to adjust to the post-Cold War era. Despite his ideological bent, he never tried to turn the sympathetic Russian leaders like Narmonov or Golovoko into capitalists or libertarians.

But trying to accept Jack Ryan in a world where not only is the leader who ran Venezuela into the ground NOT a Marxist, but a nationalist, whose right-hand man complains about his daughter's leftist friends, and their admiration of the "social justice"-platformed female opponent, is asking too much.

You could have a made up country, like Wakanda, and give it whatever government you want, and even if it's implausible, it does not break the contract to suspend disbelief. You could invent a fake backstory for World War Two where a made-up German agency was responsible for the Holocaust, or carried out elite operations that had to be stopped by the heroes' predecessors. But you can't turn around and say that the Holocaust was carried out by a dictator who was a Social Democrat, just because it's a more personally appealing narrative.
