I am not the only one who has noticed the U.S. fanning the nuclear proliferation flames. This is Richard Haas, “President Emeritus of the Council on Foreign Relations”.

another type of proliferation now merits attention: vertical proliferation, namely, increases in the quality and/or quantity of the nuclear arsenals of the nine countries that already possess these weapons. The danger is not only that nuclear weapons might be used in a war but also that the possibility of war would increase by emboldening governments – like Iran in the scenario above – to act more aggressively in pursuit of their geopolitical goals in the belief that they may act with impunity…

It all adds up to a dangerous moment. The taboo associated with nuclear weapons has grown weaker with time; few were alive when the US used nuclear weapons twice against Japan to hasten World War II’s end. Indeed, Russian officials have hinted strongly at their readiness to use nuclear weapons in the context of the war in Ukraine…

Three and a half decades after the Cold War’s end, a new world is emerging, one characterized by nuclear arms races, potential new entrants into an ever less exclusive nuclear-weapons club, and a long list of deep disagreements over political arrangements in the Middle East, Europe, and Asia. This is not a situation that lends itself to a solution, but at best to effective management. One can only hope the leaders of this era will be up to the challenge.

We are not “pursuing our national interests” if we ignore actions other countries are likely to take in response to our actions. This is just simplistic, childish thinking.
