@snood,
You're easily scared.
Everything is relative, but there is absolutely no reason to think we are remotely close to an armed conflict with Russia.
As for North Korea, apparently you don't remember the blustering of the Beloved Leader III during the Obama administration. It doesn't matter who is president or what they say, NK dictators threaten us.
It may make you feel better to know that very recently China issued a very stern warning to NK: If they cross China's "bottom line" they will be severely punished.
If in the face of warnings from the US and China NK does something insane will you blame Trump?
Of course you will.
Better we just hide away in a closet and let the insane fat boy have his way.
