You clearly prefer ideology to evidence and reading what I wrote: SOVIET commander Arkhipov saved the world from nuclear war by refusing to provide the third launch code necessary to fire his submarine's missile. Watch the documentary about him.

"On 27 October 1962, during the Cuban Missile Crisis, a group of 11 United States Navy destroyers and the aircraft carrier USS Randolph located the diesel-powered, nuclear-armed Foxtrot-class submarine B-59 near Cuba. (The B-59 was one of four Foxtrot submarines sent by the USSR to the area around Cuba.) Despite being in international waters, the United States Navy started dropping signaling depth charges, which were intended to force the submarine to come to the surface for identification.

By then, there had been no contact from Moscow for a number of days, and although the B-59's crew had been picking up U.S. civilian radio broadcasts earlier on, the submarine was too deep to monitor any radio traffic, as it was busy trying to hide from its American pursuers. Those on board did not know whether war had broken out or not.[6][7] The captain of the submarine, Valentin Grigoryevich Savitsky, decided that a war might already have started and wanted to launch a T-5 nuclear torpedo.

Unlike other Soviet submarines armed with the "special weapon", where only the captain and the political officer were required to authorize a nuclear launch, three officers on board the B-59 were required to authorize the launch because Arkhipov was also the chief of staff of the brigade (not the commander as is often incorrectly reported, who was in fact Captain First Rank Agafonov Vasili Naumovich).[9][10] The three men were Captain Savitsky, Political Officer Ivan Semyonovich Maslennikov, and Executive Officer Arkhipov. An argument broke out among the three of them, with only Arkhipov against the launch."

Although Arkhipov was only second-in-command of the B-59, he was also the chief of staff of the flotilla. According to author Edward Wilson, the reputation Arkhipov had gained from his courageous conduct in the previous year's K-19 incident played a large role in the debate to launch the torpedo.[8] Arkhipov eventually persuaded Savitsky to surface and await orders from Moscow. His persuasion effectively averted a nuclear war that likely would have ensued if the nuclear weapon had been fired.[12] The batteries of the B-59 ran very low and its air conditioning failed, which caused extreme heat and generated high levels of carbon dioxide inside the submarine.[13] It surfaced amid the U.S. warships pursuing it and made contact with a U.S. destroyer. After discussions with the ship, B-59 was then ordered by the Russian fleet to set course back to the Soviet Union."

It's well documented that some of Kennedy's generals wanted to launch a preemptive strike, which JFK rejected. From the Cuban missile crisis Wikipedia page:

"When this was reported to President John F. Kennedy, he then convened a meeting of the nine members of the National Security Council and five other key advisers, in a group that became known as the Executive Committee of the National Security Council (EXCOMM). During this meeting, President Kennedy was originally advised to carry out an air strike on Cuban soil in order to compromise Soviet missile supplies, followed by an invasion of the Cuban mainland. After careful consideration, President Kennedy chose a less aggressive course of action, in order to avoid a declaration of war. After consultation with EXCOMM, Kennedy ordered a naval "quarantine" on October 22 to prevent further missiles from reaching Cuba.[5] By using the term "quarantine", rather than "blockade" (an act of war by legal definition), the United States was able to avoid the implications of a state of war.[6] The US announced it would not permit offensive weapons to be delivered to Cuba and demanded that the weapons already in Cuba be dismantled and returned to the Soviet Union.

After several days of tense negotiations, an agreement was reached between Kennedy and Khrushchev: publicly, the Soviets would dismantle their offensive weapons in Cuba and return them to the Soviet Union, subject to United Nations verification, in exchange for a US public declaration and agreement to not invade Cuba again. Secretly, the United States agreed with the Soviets that it would dismantle all of the Jupiter MRBMs which had been deployed to Turkey against the Soviet Union. There has been debate on whether or not Italy was included in the agreement as well. While the Soviets dismantled their missiles, some Soviet bombers remained in Cuba, and the United States kept the naval quarantine in place until November 20, 1962."

Nobody is proposing basing nuclear weapons in new NATO members Finland and Sweden. Nobody with any sense would want them in Ukraine or the Baltic States. So your middle paragraph is utter nonsense.

Whose side would you have been on in:

1. The Berlin airlift in 1948?

2. The USSR-sponsored North Korean invasion of South Korea launched on June 25, 1950.

3. The Soviet repressions/invasions in East Germany in 1953, Hungary in 1956, Czechoslovakia in 1968, the declaration of martial law in Poland by General Jaruszewlski in December 1981, the Soviet invasion of Afghanistan on December 31, 1979?

4. The mass deportations of 20-25% of the populations of Estonia, Latvia and Lithuania in 1940-41 and 1949? The Soviet invasion of eastern Poland on September 17, 1939? The Soviet massacre of 20000 Polish officers at Katyn in 1940? The planned famine Holodomor of 1932-33 that killed more than 4 million Ukrainians?

I recall no American equivalent of #4. But enlighten me if you can find one in the 20th century.
