What do you believe is impossible?
Perhaps invasion of some of those countries is unlikely BECAUSE they have nukes ? You can reject all the suggestions you wish but facts are facts and nuke nations don't tend to get invaded , even by us ( the world police/imperialist).
So more nuke nations= less invasions is a reasonable albeit not a control freak friendly , conclusion.
And that is the bottom line which trumps ( yes pun intended) your party line.
When do you believe the Cold War began?
The United States, Russia, the UK, France, China, North Korea, India, Pakistan, and Israel all control some nuclear weaponry. Russia and the US share 93 per cent of all nuclear warheads,

How likely is it that the US, Russia, the UK, China, India, Pakistan and North Korea would be invaded? Only Israel is realistically in danger.
Your suggestion is noted and rejected.
If Iran approaches their breakout date every nation in the Middle East will have their own crash programs to build and deploy usable nuclear weapons. It seems like a foolish strategy.
