The state of diplomacy between the US and Cuba

President Donald Trump told reporters on Air Force One yesterday that the US is in talks with Cuba. Meanwhile, Cuban officials say there are no high-level negotiations underway, but acknowledge that some messages have been exchanged. Peter Kornbluh, co-author of "Back Channel to Cuba: The Hidden History of Negotiations Between Washington and Havana," tells The World's Host Marco Werman that diplomacy and negotiations are possible, and even preferable, in ending the current crisis between the two countries.
