Non-proliferation is a dead end. No one trusts the US to act in good faith. Any nation that doesn't get a nuclear warhead and point it at Washngton DC knows they're just one American Presidential scandal away from getting their teeth kicked in.
An alternative, as always, is to work towards our strengths as middle-powers. Remain steadfast in our pursuit of diplomatic and economic ties. Make the world too complex and intertwined to make invasions practical.
And of course, while Russia is the leader in this area, it's not the only country that could balkanize the US through "peaceful" means.
USA dispatching strikes at will based on incoherent reasons, is just another reason why everyone needs nukes now. And they need them before they are an active target, because yes, it takes years.
And no, it is not about Iran being evil. Trump does not care about that at all. He even wanted to keep the regime as is (to the extend there was a vague concept of a maybe plan).

That made everyone vulnerable to Trump.
