David Sanger on North Korea summit, lack of deterrence for cyberattacks
New York Times national security correspondent David Sanger covered the historic summit between President Trump and North Korean leader Kim Jong Un. He writes in the New York Times: "If Mr. Trump allows this negotiation to become about limiting the North’s capabilities, rather than eliminating them, he will repeat the moves that he castigated Mr. Obama for making in Iran. If he insists on getting it all — 'complete, verifiable, irreversible denuclearization,' he risks coming up empty-handed." Sanger is also the author of a new book, "The Perfect Weapon: War, Sabotage, and Fear in the Cyber Age." Sanger joins "CBS This Morning" to discuss this week's summit in Singapore and the rise of cyberwarfare.
