sigh .. on several levels
There’s far worse band names.
At that, it’s only a name. Sort of like what we ascribe to stars or galaxies, like Andromeda or Arcturus.
The band’s name comes from a phrase uttered in the early 80’s by former California Senator Alan Cranston (a man who makes Harry Reid look like a genius by comparison) warning about “nuclear megadeath” coming to America if we didn’t agree to ban all nuclear weapons and give the Soviets everything they wanted. They just changed the spelling to make it fit better on t-shirts. :)
