Nuclear weapon can be used if domestic existence threatened
It looks very scary that nuclear 3rd world threat is very visible in the media? This reminds us of the movie "Twilight last Gleaming" and even Crimson Tide. The scene of nuclear winter and end of the world suddenly becomes surreal.
Indeed will Putin pull the nuclear trigger. Many say he is a good man and is Christian and will do nothing to even think of doing these despicable thing. But he does.
Brought to the the brink by the economic sanctions and the aiding by Western countries of Ukraine, the possibility is he will.
Only prayers perhaps, miracle a event just like conversion of St Paul can change the situation and give enlightenment to Putin
In the meantime the Preppers are right and most likely to form the core of the new generation.
