I was stating what I believe to be a true counter-factual. If every western country had 1 nuke, the world would be safer than if a single country has all the nukes.

The west is also not "my side". I have no stake in most western countries, and their success or failure is not something I feel as part of my day-to-day. I'm glad there is more than one, so if something goes wrong I can go to another one.

The west gets special treatment because it is filled with prosperous democracies. Democracies are relatively stable, and rarely do things outside their Overton windows, like launching a nuclear weapon unprovoked. Prosperity is what makes people peaceful. Prosperous people have more to lose. No one in the west wants to backslide towards a state of nature because an invasion or unprovoked conflict went the wrong way.
