Could be because we have learned and seen the horrible aftermath
One thing that we can say for certain after learning about world history is that people DON'T
learn from past mistakes.
Add that to the fact the fear if someone was stupid enough to use one....... their country would be turned into a pile of glass.
I think you'd be wrong here, Johnny. If Russia used limited nuclear strike on one or two Polish cities and military objects - do you think the US would risk total annihilation of their country by answering with a nuclear strike against Russia? Certainly not, and nobody in Poland is naive enough to believe that they would. Hence, the necessity to have our own nuclear weapons. Our geopolitical position is extremely difficult, certainly more difficult than that of France for example - they border Spain, Italy and Gemany for crying out loud. :) Yet, nobody protests France having nuclear weapons. Even Pakistan is allowed to have them, so I can ask again - why not Poland?
Well your nightmares are not one of them.
These are not my nightmares - it's simply something that might happen, if we don't have nuclear weapons (because nobody will use their nuclear weapons in our defence, I think that much is obvious).
