Perhaps the most complete explanation for what occurred came from President Donald Trump himself shortly after the fact. He said, in some impromptu comments, that his national security advisor had "…made some very big mistakes when he talked about the Libyan model for Kim Jong Un. That was not a good statement to make. You just take a look at what happened with Gadhafi. That was not a good statement to make. And it set us back."
Trump has a point in that Bolton was clearly suggesting that North Korea get rid of its nuclear weapons in exchange for economic benefits, but it was the wrong example to pick as Libyan leader Moammar Gadhafi gave up his weapons and was then ousted and brutally killed in a rebel uprising that was supported by Washington.
