One other reason why this is madness; the World is nuclear now, baby.
The process actually worked in Western Europe, but it took millennia (assuming this isn't just an interlude).
If you want to make that argument, then, actually, it took two Total Wars, the Holocaust and the near-total economic and (to places where people live) physical devastation of almost the entire continent to do that. I don't think that that is an acceptable level of trauma.
In all case, all the little (in comparsion to the 20th century) wars of the past just created more wars a few years down the line. Generally speaking, war begets war.
