It is true and it seems some in the military have forgotten than nobody wins a nuclear war. With so many defense scientists and rocketeers convinced that newer better weapons will mean that the US could "win" a nuclear exchange, we are pulling closer to the brink of ending life on earth. Some lessons are never really learnt. https://consortiumnews.com/2017/03/10/dreams-of-winning-nuclear-war-on-russia/

We should be thankful that cool heads still prevail, and there are those who still write to debunk these crazy ideas of a winnable nuclear exchange. These concepts should go into the some dustbin of history as other notoriously bad ideas like mutually assured destruction, and one world government, but they assuredly perhaps due to our human foibles, they are not.

If anyone still needs any repeat of the message: lets have a message from the russian president about what he thinks of a winnable nuclear war. Unless winning is to commit assisted suicide. http://www.express.co.uk/news/world/813968/vladimir-putin-donald-trump-nuclear-world-war-three-oliver-stone-interviews-showtime
