Probably not, any more than WW2 or WW1. That never stopped the human race in the past.
The real tragedy of human nature is that fools only lose their thirst for war once they have lost everything else that matters to them. They realize then how utterly meaningless it is, when it is too late to make a difference. They sit in the rubble and weep at their own stupidity.
Wait, we're not done yet. This isn't the real tragedy.
The real tragedy is that mankind forgets whatever it supposedly "learned" from all this carnage every two generations. Forgets it altogether.
The difference now is nuclear weapons and other technology. That makes this generation's cyclic "lesson" a particularly bitter pill to swallow. Envy the survivors of the two previous world wars because they had a cakewalk compared to what this generation of men will be facing. They are ill prepared to face anything, much less global thermonuclear war.
