During the Cold War, the United States placed nuclear missiles in several locations, most notably in Europe, Turkey, and the Pacific. Key deployments included the Jupiter missiles in Turkey and Italy, and the Polaris submarines in the Atlantic and Pacific oceans. These placements were part of a strategy to counter the Soviet Union's nuclear capabilities and to ensure a rapid response in case of conflict. The presence of these missiles contributed to heightened tensions during the Cold War, especially during events like the Cuban Missile Crisis.

At the highest number, it was less than 1500, with 1000 of these Minuteman missiles.
The closest we came to a nuclear confrontation with Russia that I know of, was under John F. Kennedy during the Cuban Blockade in 1962.
