Why is Trump kissing North Korea’s ass?

Why is Trump kissing North Korea’s ass while taking hostile action against South Korea?

There is no reasonable reason to appease North Korea in any way.  They are the USA’s enemy.  They are an enemy of God himself for many reasons.

North Korea is an ally of Russia.

The USA should treat North Korea as an enemy not a friend.

Trump seems to be acting against the USA’s good in many ways.
