A liberal democracy inevitably leads to the interventions that the US has made. Liberal democracy works the same as international communism. It’s a utopian belief that its form of government can bring peace and prosperity to the world, and this leads its elites to support military interventions with the intention of spreading liberal democracy abroad. If nations simply abandoned liberal democracy and ruled themselves as autocracies based on their own culture and historic destiny, there wouldn’t be any reason for the US to intervene militarily abroad.
