The people in the Trump administration who would be directly familiar with Truman’s threats of nuclear war are his military Generals. But none of them would ever have put that quote in his mouth, because they’ve lived war, and they know better. Nor would any of Trump’s children have steered him in that direction. But as it turns out, “Fire and Fury” is the name of a mission in the video game World of Warcraft. And guess which Trump adviser has a professional and financial history with that particular video game company?
