(CNN) The now-canceled summit between the United States and North Korea pitted President Donald Trump against President Donald Trump. On the one hand, Trump fashions himself as a historic figure -- someone able to do things no one else can (or even thinks about). A summit with North Korean dictator Kim Jong Un was, even as recently as six months ago, a totally outlandish proposition. Once proposed -- a message carried to the White House by South Korea -- Trump leaped at the opportunity. On the other hand, Trump has built his entire adult life on the concept of deal-making -- a critical piece of which is knowing when to walk away from a bad deal.
