"We come in peace":
"There was some talk about the Libyan model last week," Pence said in an interview on Fox News. "As the President made clear, this will only end like the Libyan model ended if Kim Jong Un doesn't make a deal."
That worked well, didn't it?
Given NK concern over Libya as an example f no nukes = regime change, throwing that comment appears to me to be targeted to create a reaction that allows US to cancel the summit. The US doesnt want a summit or peace. As that means SK as an ally is diluted, and China is a bigger force, as in more hands on = USA shut out
