The total death toll in Vietnam is estimated to be over 4 million, all parties included. When compared with the bombings of Hiroshima and Nagasaki, which exacted a toll of perhaps a half million if long term disease is factored in, what would have been the result had LBJ ordered a nuclear strike on Hanoi? Would such action have irked Russia into retaliatory behavior? Would the net loss have been reduced? I know-it's hypothetical, just wondering what you students of history and war have to say on the matter.
