The Nobel Peace Prize gave their award this year to Nihon Hidankyo, representing the survivors of the nuclear bombing of Hiroshima and Nagasaki. The point was to emphasize that nuclear weapons should never be used again under any circumstances and must be abolished.
US policy has been for decades that if required, the United States would reserve the right to use nuclear weapons in response to a conventional, biological, or chemical weapons attack on the United States and its allies.

For example, during the entirety of the Cold War, the United States did not match the Soviet armies tank for tank or artillery piece for artillery piece in central Europe. President Eisenhower understood such a large conventional force would bankrupt the United States.

While the US had 423,000 troops in Europe and Asia at the height of the Cold War, it was assumed that a Soviet tank army attack through the Fulda gap into Western Germany or a North Korean attack on the ROK or a PRC attack on Taiwan, might very well require the United State to respond with nuclear weapons. The US and its Pacific or NATO allied forces, while formidable, were not necessarily sufficient to hold the line.

This promise by the United States was called extended deterrence. Washington would extend its deterrent nuclear umbrella over the NATO allies in Europe and Western Pacific allies as a security guarantee. In this way, the Soviets could not swallow one NATO country after another because any attack on one NATO nation was considered an attack on the entire alliance. In the Pacific, an attack on a US ally would be considered an attack on the United States as well. With the collapse of the Soviet Union and the end of the Warsaw Pact, NATO remained and added a considerable number of nations that were previously allied with the Soviet Union. These nations did not want to remain in security limbo between a new Russia and an old NATO. These nations joined NATO to feel secure.

Now the CFE or Conventional Forces Europe treaty of November 1990 did confirm the most dramatic reduction in conventional forces in history, but the concerns of the former Soviet empire states were confirmed when in 2007 Russia suspended its participation in the treaty and in 2015 completely halted its participation and then withdrew from the treaty altogether in 2023. As a military force, NATO was relatively formidable but not postured to be an offensive factor in central European security. It literally posed no threat to Russia’s security. However, with Russia’s growing nuclear forces plans initiated in part by the 1999 Yeltsin decree calling for the development of battlefield nuclear weapons, and Mr. Putin at the helm, Russia came to be seen as a growing threat. With Moscow’s invasion of Moldova and Georgia in 2008 and Ukraine in 2014 and 2022, for most of Europe, the extended deterrent of the United States was deemed essential to protect their security.

The Biden administration did consider adopting a nuclear policy known as “No first use.” The theory was that if all nuclear armed nations pledge not to initiate the use of nuclear weapons, then nuclear weapons will remain deployed but never used, and in this way their salience as a security measure can be gradually reduced to where abolition becomes a real possibility.
However, the US extended security guarantee to Europe was based on the United States explicit willingness to use nuclear weapons in retaliation to an attack, with the long-standing assumption that a nuclear conflict could very well grow out of a conventional conflict.
This was also true for our extended guarantee we had traditionally provided for Japan and the Republic of Korea. Part of the guarantee was symbolized by the deployment of multiple thousands of small, regional, theater nuclear weapons, such as Tomahawk cruise missiles, deployed in both Europe and Asia.
