New York Times: “In one of the starkest back-to-the-Cold War moments yet, Mr. Putin’s visit Wednesday to Pyongyang — and the announcement of a pact to provide “mutual assistance in the event of aggression” — underscored that efforts by the world’s three biggest nuclear powers to halt nuclear proliferation by North Korea had been dying for some time. Mr. Putin and Kim Jong-un, the North’s leader, just presided over the memorial service.”
“Mr. Putin did far more than drop any semblance of a desire to ensure nuclear restraint. He promised unspecified technological help that — if it includes the few critical technologies Mr. Kim has sought to perfect — could help the North design a warhead that could survive re-entry into the atmosphere and threaten its many adversaries, starting with the United States.”
