You never know if a party is going to act in good faith until you actually, you know, try and negotiate with them.
Yes, we've never tried to negotiate with North Korea before. As a result, there were also no North Korea experts accurately predicting exactly what would happen here.
I never said we hadn't tried to negotiate with North Korea before.
So, while there was minimal at best engagement with North Korea (okay, none), they were using Soviet ICBM designs to build better missiles and then they started launching them all over the South China Sea and over the heads of our allies. While there was minimal engagement with North Korea (okay, none) they were developing smaller and more powerful Nukes.
Barrack Obama paid for a shitty unsigned Iranian nuclear deal, but wouldn't engage a country that already had nukes and was getting better ICBM's. Weird tactics for a guy who won a Nobel Peace prize for
talking about eliminating nuclear weapons.
