You kidding? Avoided nuclear war? He brought the country to the brink of nuclear war not from nuclear war. Which isn't saying he did the wrong thing it is just saying it could have turned out much differently.
At that time, the US vastly outclassed the Soviets nuclear forces. Had it become a shooting war, we'd have faired far better than the Soviets. The Soviets knew this and backed down. It's why they tried putting missiles so close to US targets. Their guidance systems sucked and could never have been tactically effective from Russian bases. So President Kennedy's pressing was akin to our holding a fully loaded gun on someone doing the same but with just one shot left. Not being any more suicidal than us, they did what we knew they must - back down.
Believe what you want but "faired better" is not a winning hand. The soviets had submarine launched missiles off of our shores, it would have been ugly. Khrushchev blinked that is what happened. Kennedy challenged an unpredictable leader and got away with it, thankfully.
What you actually had were two countries who had no desire to ignite the world. Vying for power? Yes, that is natural. Trying to expand territory, and trade routes etc? Yeah, that is what virtually every war is about, unlike what the narrow minded moronic liberals will tell you (they think every war is over the bible.)
The fact that there was a desire on both sides to avoid nuclear war, it never happened. With these dirty ass sandniggers though, it is entirely different. If and when one of those fanatics get their hands on one of those, it is only inevitable.
Nuclear holocaust has been inevitable since Einstein discovered how to split the atom. Guided by Murphy's law and from the days the prophets, it is inevitable.
"Have no fear of atomic energy, cause none of them can stop the time." Bob Marley.
The bottom line is those fanatics are not as fearful of death and do not hold the same value of life as rational thinkers.
