I just came here to point out that even nuclear weapons were a slow takeoff in terms of their impact on geopolitics and specific wars. American nuclear attacks on Hiroshima and Nagasaki were useful but not necessarily decisive in ending the war on Japan; some historians argue that the Russian invasion of Japanese-occupied Manchuria, the firebombing of Japanese cities with massive conventional bombers, and the ongoing starvation of the Japanese population due to an increasingly successful blockade were at least as influential in the Japanese decision to surrender.
After 1945, the American public had no stomach for nuclear attacks on enough ‘enemy’ civilians to actually cause large countries like the USSR or China to surrender, and nuclear weapons were too expensive and too rare to use them to wipe out large enemy armies—the 300 nukes America had stockpiled at the start of the Korean War in 1950 would not necessarily have been enough to kill the 3 million dispersed Chinese soldiers who actually fought in Korea, let alone the millions more who would likely have volunteered to retaliate against a nuclear attack.
The Soviet Union had a similarly-sized nuclear stockpile and no way to deliver it to the United States or even to the territory of key US allies; the only practical delivery vehicle at that time was via heavy bomber, and the Soviet Union had no heavy bomber force that could realistically penetrate western air defense systems—hence the Nike anti-aircraft missiles rusting along ridgelines near the California coast and the early warning stations dotting the Canadian wilderness. If you can shoot their bombers down before they can reach your cities, then they can’t actually win a nuclear war against you.
Nukes didn’t become a complete gamechanger until the late 1950s, when the increased yields from hydrogen bombs and the increased range from ICBMs created a truly credible threat of annihilation.
