Report: Pentagon to make changes to Nuclear communication system

General John Hyten, head of U.S. Strategic Command, has delivered a classified report overhauling nuclear communications for President Trump that offer "specific new details of top Pentagon leaders' views on nuclear weapons," to Defense Secretary Jim Mattis, CNN's Barbara Starr reports.

Why it matters: Starr details the "changes are critical in the wake of months of tensions with North Korea and uncertainty about Russian intentions. Including conventional military options — such as cyber or missile defense — gives a President specific options in a crisis for de-escalation, something Hyten continues to advocate."
