"The latest move of the hands was precipitated by the recklessness in Trump’s nuclear thinking and the deepening crisis over Korea. Trump wondered aloud about the point of having nuclear weapons if he couldn’t use them. His answer was to make them more usable, which he did with his new Nuclear Posture Review (NPR), the first since Obama’s 2010 NPR, which had reduced the role of nuclear weapons in the US defense posture. The 2018 NPR significantly elevated their role, permitting use in response to vaguely defined “extreme circumstances,” such as cyberattacks or attacks on the infrastructure of both the United States and its “allies and partners.” The review doubled down on Obama’s unconscionable 30-year trillion-dollar modernization of all parts of the nuclear arsenal. The actual cost looks to be closer to $1.7 trillion and climbing. To make matters worse, all eight other nuclear powers are undertaking their own modernizations, though on a far more modest scale. Russia, it should be noted, actually cut its defense spending this past year."
