Most Americans continue to hope for the best, even if Trump gets the credit.
Most, not all.
So here's the thing.
North Korea is a sovereign nation. They have the right to own nukes.
We have learned to live with other nations with nukes which were far greater existential threats to the US.
The mistake most people are making is equating "the best" with "no nukes in North Korea".
That just is not going to happen. The sooner the fuckwits like Trump figure that out, the sooner we will arrive at "the best".
"The best" would actually be to move North Korea incrementally toward a market economy, like we did with China.
The more a country moves toward a market economy, the less totalitarian they become.
That's how you beat the ******* commies. With STUFF!
