This discussion is already looming in Germany, especially now that Elon Musk openly wants the US to leave NATO. There is a standing offer by Macron for Germany to go under French nuclear protection. The UK also appears to be more than willing to fill in the nuclear vacuum left by the US. If things continue the path of the last 2-3 weeks, I am sure that at some point there will be a discussion about whether Germany should prepare to be able to at least build nuclear weapons quickly.
I have a feeling that Canada has similar thoughts. I wonder what would happen if they started developing nuclear weapons. The US president already announced he would make Canada the 51st state, and around 25% of Canadians saw the US as an enemy country 2 weeks ago [0]
Strategically, it does not make any sense to me. I am pretty sure that the Russians are just as confused. I wonder if there is a historic precedent of a country giving up a functioning empire voluntarily, without any internal or external pressure to do so.

This is one reason Britain and France are out front right now on matters of European security.
It's too late to cancel now, but I guess in the future we will have to reconsider the true value of these bombs and airplanes. Once we really need them, US might "force us into peace".
With the US now showing they are not afraid of doing a "rug pull" on agreements, one starts to wonder if the Netherlands shouldn't start development of nuclear weapons again.
