KJU sent Trump a birthday card. They shook hands at the border and Trump stepped foot on North Korean soil. It's not a bad thing. If a personal relationship between the two men can keep talks going, I'm all for it. The goal here is nuclear disarmament. Or at least control. If Trump's "hand of friendship" can keep that goal on the table, at least, we are all winning.
Kumbaya!
It's amateurish. Reliability and trust are the important factors in an agreement between nations, not personal feelings. Trump relentlessly proves he can't be trusted, and he extended that policy to include the US. Sure, the 'hand of friendship' doesn't hurt, but it's no substitute for professionalism.
