During the cuban missile crisis back in 1960ish, R̶u̶s̶s̶i̶a̶n̶ Soviets actually had reached the point where they had launch-ready, on-ramp nuclear missiles.
We learned some 20 years later that the US had deployed nuclear missiles of their own in Turkey, and the agreement was to remove those missiles in return.
Back in those days, we had no "nuclear suitcase" for approving a nuclear launch,
and we had US warships surrounding Cuba ("quarantine", brilliant Pres. Kennedy!), themselves encircled by Soviet nuclear-equipped submarines.
I'm glad these men knew what is war like, and didn't get humanity dragged into a MAD, like all of these civilians today are trying to do.
Let's just do a cease-fire, whatever the reason, let's just stop firing, and let's talk.
The enemy is the enemy, this is what it is, but let's not forget, quoting Hemingway, that they are the enemy just because we were born on this side of the mountain, and them on the other side.
If we dehumanize the enemy, what are we then?
