You don't think it's enticing to the north koreans to become a wealthy, technologically advanced state without losing their control over their country? Seriously? Instead of the usual "diplomacy" which is us threatening to flatten them if they step out of line, we are now using the carrot instead of the stick. "say, if you'll be friendly with us maybe we can help you become more prosperous" is a lot more enticing than "do what we say you backwards savages or we'll turn your country into a crater", no?
He's the first US president to actually bother even TALKING to the north korean leader in person, yet you say there's no diplomacy? You're a partisan moron, blinded by your hatred for the president.
