Something extraordinary did happen, a UNSC Member, who happens to have contested status since 1992 has threatened nuclear war on a substantial number of UN countries. Yours included.
I lived through and served in the cold war. My ASW warfare specialty was in part concerned with keeping an eye on and hoping to neutralize (or sink) submarines filled with nuclear weapons.
The ever present threat of nuclear war was a daily concern as I grew up and grew into adulthood.
Not sure what is behind your shrill overreaction here. It's a threat, yes, and I not pleased that it was made.
(I doubt many people are, to include some important people in Moscow who are not the president).
Nothing extraordinary in governments making threats and talking big.
Hell, Mr Kim in North Korea has been doing that on and off for years.
