Trump and North-Korea Politique et gouvernements

Hi every one! Yesterday, Donald Trump met Kim Jung Yun again and the american president came in North Korea for the first time. Then, Trump invited officially Kim to come in USA.
For me, this situation is akward9 and i'm afraid that USA shares values of North Korea.
What do you think about it? What is your feeling?

trump and kim are 2 people where you never know what they are going to do and what they are up to. And those 2 together is not really a good combination because something can happen that the world is not waiting for.

also bad is that they say something and do something else
