The concept that a few gimmicks like nuclear artillery keeping the Soviets from steamrolling through Western Europe seems minuscule compared to the serious threats of the main battlefield nuclear weapons like rockets, missiles and bombers as well as the strategic nuclear forces that would probably get called in to drop the big city-killers in order to affect the war (stop the fighting, retaliate against tactical nuclear weapons being used, or escalate to total nuclear war).
Besides, the Soviets, after acquiring so much territory after WW2 and later controlling China (until their relationship soured in the 1960s), they were content to foment, support and supply communist revolutions around the world rather than direct military confrontation with the Western and capitalist powers.
- US Convair B-36 "Peacemaker", a United States Air Force (USAF) strategic bomber operated from 1949 to 1959.
The B-36 was the largest mass-produced piston engine aircraft ever made. It had the longest wingspan of any combat aircraft ever built, at 230 ft (70.1 m). The B-36 was the first bomber capable of delivering any of the nuclear weapons in the U.S. arsenal from inside its four bomb bays without aircraft modifications. With a range of 10,000 mi (16,000 km) and a maximum payload of 87,200 lb (39,600 kg), the B-36 was the world's first manned bomber with an unrefueled intercontinental range. The B-36 was the primary nuclear weapons delivery vehicle of the Strategic Air Command (SAC) until it was replaced by the jet powered Boeing B-52 Stratofortress (which first became operational in 1955). The B-36 set the standard for range and payload for subsequent U.S. intercontinental bombers. https://en.wikipedia.org/wiki/Convair_B-36_Peacemaker
