No one in the US government wants war, few if any of the rest of the world community want a war.

No one wanted a war in Europe in the '30's....unfortunately two individuals did, Hitler and Stalin,  both conspired to precipitate WWII.

Just like Hitler and Stalin, there is one person in North Korea who may well want to precipitate a war .

He is the one with ICBMissiles , he who has nuclear war heads, who has been testing his missiles by shooting them over Japan and has threatened repeatedly to shoot his missiles to hit the USA and its allies.

If he initiates a war, President Trump would, quite rightly, end it.
