Absolutely. One of the contributing decision factor in the shot down of the Korean Air Lines Flight 007 was just that.
"Aircraft from USS Midway and USS Enterprise repeatedly overflew Soviet military installations in the Kuril Islands during FleetEx '83, resulting in the dismissal or reprimanding of Soviet military officials who had been unable to shoot them down."
"The end in this case meant not just the fate of the submarine and its crew, but potentially the entire world. Cut off from outside contact, buffeted by depth charges, its air conditioning broken, and temperatures and carbon dioxide levels rising in the sub, the most obvious conclusion for the officers of B-59 was that global war had already begun. But the sub had a weapon at its disposal that US officers didn’t know about: a 10-kiloton nuclear torpedo. And its officers had permission from their superiors to launch it without confirmation from Moscow.
Two of the sub’s senior officers wanted to launch the nuclear torpedo. That included its captain, Valentin Savitsky, who according to a report from the US National Security Archive, exclaimed: “We’re gonna blast them now! We will die, but we will sink them all — we will not become the shame of the fleet.”"
It seems the credit actually should go to Vasili Arkhipov.
Cold wars are GOOD.
Cold wars are how you prevent hot wars, and also how you prevent powerful aggressive countries from annexing and colonizing people at will.
Missiles in Cuba were a USSRs response to US nukes in Turkey, so I am not sure I understand your point.
In 1968, my dad spent a year at Galena AFB in Alaska. This was the closest base to the USSR. Their entire job was to counter the Soviet incursions. The Red Air Force was constantly testing and probing and provoking the US air defenses.
The usual thing was the Soviets would send over a bomber. Once they got close enough, Galena would send out a fighter or two to snuggle in close and let the bomber know that we saw 'em and we'd bwast 'em if they came any closer.
It was the cold war, and that's how it was played.
