Catch 22, do you unilaterally disarm your nuclear weapons and risk being overrun in the future by larger superior land, air and sea forces from bigger nations, or hang on to a deterrent you will most likely never use? It’s not an easy one to answer but all nations with nuclear weapons, ourselves included, know that once a long range warhead is launched in anger towards another similar armed nation it’s pretty much game over for mankind. The destructive power of modern day nuclear weapons is mind blowingly scary compared to Hiroshima in 1945.
