And once somebody starts it using nucleur, won't all the rest, good, bad and ugly, have to jump-in, knowing that if they don't use it they possibly will loose it by retaliatory and possible misguided strike/settling separate third party scores ?

So there may be a lot of smacking of the wrong bottoms.
