How'd you arrive at this conclusion? Wars happen when enough people are willing to sacrifice themselves and others. Leaders sacrifice their own, foot soldiers sacrifice themselves and their enemies. What makes people willing to sacrifice? An opportunity/threat for a significant shift in quality of life. I don't think democracy, dictatorship or any other form of government or its customs make much of a difference at all. You can have stable dictatorships and unstable democracies - it's got much more to do with luck and sometimes competence of the people at the top.
