Hmm I don’t think so. If it is true those are over the ocean or something. I mean an attack with 100 missiles would destroy nearly any country. Russia is especially vulnerable because they only have a couple of cities with any population in them. Modern nukes are 50-75x the yield of the ones they dropped on Japan. There are all kinds of externalities. They can poison the ground water for generations. They can kill any life feeding in the area. They can cause fallout which is like a radioactive dust cloud covering everything. It isn’t good.
