Two World Wars, millions of deaths and the subjugation by conquering powers of one of participants isn't a process we really want to repeat to solve other conflict zones. The process whereby nations are built from multiple ethnic groups, and then nationalism and international tension is replaced by international co-operation seems to me to be one that we can't say reaches a stable state. The Cold War hasn't been over for that long, the European financial crisis has revealed some pretty ugly attitudes between various European polities. Perhaps the democratic peace thesis is right, however it is also possible that France and Germany kick off again in our lifetime.
