I don't know. We came extremely close to nuclear war several times, and each time it was people refusing to obey their training and follow orders that has saved us.
And then one man has saved us all by refusing the launch nuclear strike on US despite Soviet satellites confirming multiple launches from US heading to CCCP. He decided to wait for radar confirmation first despite everyone above him(and next to him) approving the counterstrike. If he followed his training we'd all be dead now.
