Carnegie’s George Perkovich spoke on the President’s Inbox with the Council on Foreign Relations’ James M. Lindsay and Robert McMahon about President Donald J. Trump’s options on North Korea’s nuclear weapons program. Perkovich explained how treaties obligate the United States to come to the aid of South Korea and Japan if North Korea should act aggressively toward them. However, he added, as North Korea develops an array of missiles that could deliver a nuclear weapon to the continental United States, that further complicates the tension over defending U.S. allies in the region. Perkovich discussed the nature of sanctions, adding that there is no evidence that tighter sanctions would make the Kim family give up their nuclear weapons.
