DO you think, it's inevitable? For NPT to lose meaning and nations after nations going nuclear?
OR will both China and US already have an understanding to not birth another nuclear radical state ?
My reply was conditional that if Ukraine/ anyone else gets the nukes. Right now Geostrategic equations are very dynamic and balancing is becoming very tough, Belarus is already got nukes under Russian umbrella, US has already shared nukes to so many countries in name of nuclear umbrella, Iran regime knows that they can't survive without nukes, and if they get, Saudi Arabia/ Turkey may go for same. Further US doesn't have good relation with Brazil, and South Africa as of now, and Nukes give a kind of safety and stability to nation from external forces. West is no more strong as earlier days so as China strengthens, Japan, and South Korea have to review their strategic safety options.
One more observation I have that fear regarding nukes have decreased gradually in general, and tactical nukes went to grey area and looks like acceptable option for some scenarios. With increase of multipolar world, effect/ fear of isolation is also coming down, North Korea and Iran are good example of this. So getting to new equilibrium for world is becoming difficult with each passing day.
All these things leading world to greater conflicts, as history teaches us major power shift comes along with major war. Every important Nation is preparing for it as we can see from worldwide increasing expenditure on defense.
Many experts have mentioned that last 80 years were exceptionally calm with few exceptions, and we all know how great volcanos work.
PS: The Question now a days my brain use to ponder without successful solution is that if a important island country gets nuked in major way/ thoroughly (encompassing it's major critical areas), will it ignite chain reaction world wide or not?
