This is the exact opposite of the truth. Multi-polariry always leads to war because there's no hegemon with a monopoly on force. States are in anarchy, after all. In an anarchic situation in the presence of information asymmetries and opposing interests, you always get war. Aside from nukes, unipolarity is the only reason for the unprecedented levels of peace we've seen since 1990. This is realism 101.
