Well your post and question are ignorant and false. Where did I exactly propose a first nuclear strike use or even advocate going to war?
Putin is boasting about a first strike weapons development. He did so as a result of the missile shield going up in Europe and becoming operational. He is gloating our shield can be defeated by his new missiles. If you knew he was about to use them you could use stealth insertion or special forces on the ground with non nuclear methods to prevent them from being used. If Putin did use them what is the point under MAD doctrine if you start something that ends in your destruction? China is also now boasting about developing salted nuclear warheads with heavy fallout or what Leo Szilard called doomsday weapons. So no your rhetoric is just that and I did not nor do I suggest use of nuclear weapons is ever a good idea. But they exist and are there everywhere and every despot on the planet wants one and soon they may be used again by miscalculation or megalomaniac insanity. How do you stop that, because you are never going to be rid of nukes until they are launched or retired
Paragraphs are your friend.
Go back and re read your post. You wrote, “If you first strike (at) Putin...”
That is where I got the idea.
I am glad that is not what you are advocating.
