The United States is engaged in high-stakes negotiations with North Korea over its nuclear program as the White House prepares for the summit between President Trump and North Korean leader Kim Jong-Un. But nuclear capabilities and missiles are not the only items on the negotiating table. An eventual settlement could include some difficult concessions and require significant oversight and legislative action on the part of Congress. In addition to a potential restructuring of U.S. forces in South Korea, a grand bargain could result in a range of due-outs for Congress, from sanctions relief and economic incentives to multilateral political arrangements.
