I'd say each of your three points are seriously exaggerated, but that's really neither here nor there. Why can't we be worried by the content of the emails and the fact that a foreign government hacked them and leaked them strategically to influence our election?
It strikes me as profoundly foolish to not react here just because you happen to be happy that this particular set of information was released. (As well as, by the way, reams of email with no value to the public whatsoever.)
And of course nobody is suggesting we fight a nuclear war. There's clearly plenty of space between GP's suggestion that we do more than tell them to 'cut it out' and nuclear warfare.
