Believe it or not, there’s nothing saying a communist country needs to be a one party dictatorship. It would be perfectly achievable though democracy if the majority of the population actually wanted to take collective responsibility for the country and wanted people to be treated fairly. The reason communist dictatorships fail is because they are dictatorships, not because they are communist.
If the USA attacks another NATO country, article 5 requires that the rest of NATO all pile on. None of those countries could individually do much, but you’d be loosing hundreds of thousands of soldiers and trillions of dollars to possibly take an icy rock with a population of 56000. It’s fucking stupid.
