The easy part is agreeing to a summit. The hard part is solving the problem. But that doesn't mean we should be entirely cynical. Some say insanity is doing the same thing over and over again and hoping for a different result. That could apply equally to talking with North Korea and to trying to isolate it into submission. But circumstances change, and sometimes the same action in a different context has different results. I will admit that at Stratfor, we were a bit surprised at the March 8 announcement of a forthcoming summit between U.S. President Donald Trump and North Korean leader Kim Jong Un. It is not that we thought such a meeting was impossible — far from it. Trump's defining characteristic is that he bucks conventional wisdom and the establishment, and he has said he'd be happy to sit down over burgers with the North Korean leader.
