Do Democracies Support Violent Non-governmental Organizations Less Than Autocracies Do?

This study draws attention to the question: Do democracies fight indirectly through material support to violent non-governmental organizations (VNGOs) which wage intrastate war against other states in general and against democracies in particular, or are democracies less warlike by proxy? The main conclusions are: democracies are less warlike by proxy than non-democratic states, and the more democratic the regime the lower the probability that it will support VNGOs waging war against other states, both in general and against other democracies in particular. The results do not unequivocally support both the monadic or dyadic argument of democratic peaceful behaviour.
