There are several problems when it comes to gulf states for your anecdote.

The problem isn't a stable country like Saudi having the bomb, the problem is triggering an arms race. If Iran gets the bomb then what does that mean for Lebanon? If Iran gets the bomb what does that mean for Hezbollah? If Iran gets the bomb what does that mean for Syria?

If Iraq had the bomb in the 80s what would that have meant for the Iran/Iraq war, or the first Gulf war? Saddam Hussein may have felt that nuking Kuwait as part of a scorched earth policy would've been valid. After all, he used chemical weapons against Iran (and his own people).

I can't speak for asia but in the middle east nuclear bombs change the balance of power substantially.
