Of course, I forgot that you are the owner of the truth and the knower of all objective information - for example Chomsky speaking about communism. You have to be kidding.

Anyway, please, give your version, how many people died under Stalin's regime (please include Holomordor, dying of hunger is a violent death IMO)? How many people died as a result of the invasion of France, Poland and the USSR by Nazi Germany? Hint: You will have to make some assumptions, none of that data is really uncontested.

Feel free to compare these, in reasonable terms with US wars or even US induced wars.

Bottom line, authoritarian regimes are much more prone to enter into wars. Most people by default do not want war, if given a voice, they would tend to request peaceful solutions. Tyrants need wars, countries ruled with strong military influence tend to like large armies and these tend to like waging war.
