North Korean leader Kim Jong Un left the summit with Trump in Singapore on Tuesday with four of his longstanding objectives met. Trump got little in return. First, Kim, a 34-year-old brutal totalitarian leading a famished country, met as an equal the leader of the most powerful nation on earth — an accomplishment that eluded his father and grandfather. Second, Trump “committed to provide security guarantees to the DPRK.” Third, he agreed to halt U.S.-South Korean military exercises. Fourth, Kim has reversed the U.S. policy of “maximum pressure” — witness how China is already pressing for sanctions relief. Whether or not the United Nations Security Council takes such action is irrelevant, because Beijing controls the trade flows to North Korea and will now likely ramp them up again.
