The USA at least just recently unilaterally withdrew from the INF treaty (claiming Russian non-compliance, but launching a rocket of their own that would have been illegal to even develop while the treaty was in force the day the treaty expired). Israel's well known illegal nuclear weapons are also supported by the USA.

So at least one pretty important NATO country is very clearly not prepared to get rid of its nukes, or pressure allies to get rid of theirs. Even more scarily, per president Trump, this same country is very interested in finding ways to get usable nukes.
