Possibly their leaders retained some small degree of rationality and/or empathy even at the most stressful moments (however I doubt that either the current United States president or Russian Federation president are capable of either rationality or empathy).
Possibly it was entirely sheer blind luck.
Possibly (if you are religious) God decided not to let them do it.
Possibly we will never know.
Because there was no true defense against nuclear weapons. Once both sides had nuclear weapons, the only way to "protect" themselves from the other side was to have so many more nuclear weapons that even if their enemies used all of their nuclear weapons, there would still be nuclear weapons to shoot back with. That way, nobody would use nuclear weapons, because they could never actually "win" that way. This thought process was referred to as Mutually Assured Destruction, or MAD.
The first Soviet nuclear weapon was tested in 1949. They have never used one in combat.
No, Cuba never had control of a large amount of nuclear weapons, the Soviet Union placed them their in reaction to the US placing Nuclear weapons on West Germany, Greece, Turkey, and some pacific island. The US threatened a huge invasion or nuclear strike against Cuba after they discovered the Nuclear weapons in Cuba
In war, never.
It was born on 06 August 1945, and escalated from there. There NEVER was a nuclear war. It matured with newer, faster, deadlier, bigger nuclear weapons that were NEVER used.
No, Latvia doesn't have any type of nuclear weapons and never had.
Syria has never had any nuclear weapons.

Bangladesh has never done any nuclear weapons tests. Pakistan and India usually test above ground to intimidate each other.
In war, never.
A small one, aimed mostly at nuclear power. But it never even got a functioning prototype reactor.

As far as I know nuclear weapons have never been traded between countries, so if a country has nuclear weapons it is due to their own science and technology, or to espionage activities to get the required knowledge. The other criterion is not to have signed up to the Non Proliferation Treaty, except for countries that had already developed weapons when the Treaty came into being.
John McCain believes it is necessary in this world today that the U.S. have a nuclear arsenal. He also prays we never have to use them as any sane person does. He wants to cut our supply of weapons while at the same time having enough to protect America in the event it became a necessity. These weapons are the very reason the Soviet Union never attacked up. It was called MAD, for Mutual Assured Destruction. They are necessary evil in this world as long as their are rouge nations willing to attack the U.S.
No nuclear weapons have been used since World War 2. There were testings done by Russia and possibly other countries but they were never used against other nations.
