It's been six months since President Donald Trump and North Korean leader Kim Jong Un said they came to an agreement on denuclearization, but new satellite images published this week by an independent Washington think tank showed at least 13 previously undeclared missile operating bases in North Korea.

Meanwhile, while on a trip to Singapore, Vice President Mike Pence told NBC News that the U.S. will not demand a complete list of all of North Korea’s nuclear weapons and missile sites before Trump and Kim meet for a second time next year. And while Pence has said the U.S. will keep North Korean sanctions in place for now, there are plenty of people questioning whether the Trump administration should be meeting with Kim Jong Un at all without a full list of weapons in hand. These developments come as other major international stories gain steam, including the Brexit process in the U.K. and the still-unfolding story of journalist Jamal Khashoggi’s murder by Saudi Arabian operatives potentially with the involvement of the crown prince.
