“How deep into Russia to attack (assuming no use of nuclear weapons)?”
This is the rub. They can do all the war planning they wish, but in the end, if we are losing, a few hundred or a few thousand megatons of thermonuclear power will take care of it.
*When the government and the military are run by sociopathic psychopaths, especially if No. 1 thinks nuclear wars are a great idea and the military brass have been salivating over a nuclear war since 1946, I don’t see a decent end to this unless We the People awaken and take our Constitutional Republic back, and again have the Constitution and Bill of Rights as the law of the land. That worked pretty well until we had our Reichstag fire on 9/11 and the illegal, unconstitutional, and misnamed Patriot Act put in, unread and, just like Nazi Germany, we lost our civil rights.
*For the sake of our nation, the nations of the world, and the world itself, we must awaken and, peacefully if possible, but win, lose or draw, take our nation back, put the psychopaths into rubber rooms with soft toys to play with, and go to work rebuilding what we have mangled and destroyed, domestically and globally.
*The alternative is serfdom or death for all, or nuclear Armageddon. I am a nuclear veteran and have seen that Armageddon up too close and personal. We don’t need it, nobody does.
