Looks like you were right.
Tillerson has failed to stop the Twit-in-Chief, who is so stupid/demented that he doesn't understand that Korea had three different leaders in the last twenty-five years.
(Republicans, Turmp and his actions are your responbsibility. Both because you voted for him, and because you refuse to remove him even when the evidence of gross mental incapability is staring you in the face.)
Hopefully the generals who are calling the shots in the so-called Trump administration will distract President Spoiled Brat with some pretty pictures or a Trump Is Amazing storybook and prevent war.
If he's going to attack NK, just do it and don't talk about it on Twitter for weeks in advance. I seriously doubt any kind of attack is being planned. He's just running his mouth and squandering what little credibility he has left for no reason.
There's really no big difference between how he and Kim are handling this situation. It's pretty telling where we've reached the point that you can say that about a US president. They're just tossing theatrical, empty threats back and forth, although at least in the case of Kim it kind of makes sense given the position his country is in.
If you're going to attack North Korea, why not go all the way and drop a nuke on Pyongyang?
