It's the latter. The Trump Kim summit was on par with the Madeleine Abright, Kim Jong Il champagne toast. It's not a liberal - conservative thing, it's a refusing to learn from history thing.
Well, what has history taught us?
It tells us that they have stabbed us in the back more than once after talking very nicely.
Should we expect this time to be different?
If the answer is no (and that’s the most practical answer given our history in dealing with them), what is the most practical thing we should do next?
Lol, wait!! You seem to actually believe we should have had in hand at the end of a 5 hr meeting, a signed detailed agreement specifying time limits for each step of the denuclearization process, methods of verification and all other minutiae involved in an agreement such as this.....right?
You seem ignorant of the fact this attempt is ALREADY different in that unlike previous attempts we have given up ZERO again we have given up ZERO, with ALL sanctions still in place where they will remain until complete denuclearization has taken place and has been fully verified.
You should try to keep up...really.
