ast year, a team of American diplomats from the State Department’s Global Engagement Center traveled to two dozen countries and signed a series of memoranda. Along with their counterparts in places as varied as Italy, Australia, and Ivory Coast, they agreed to jointly expose malicious and deceptive online campaigns originating in Russia, China, or Iran.

This past September, the Trump administration terminated these agreements. The center’s former head, James Rubin, called this decision “a unilateral act of disarmament,” and no wonder: In effect, the United States was declaring that it would no longer oppose Russian influence campaigns, Chinese manipulation of local politics, or Iranian extremist recruitment drives. Nor would the American government use any resources to help anyone else do so either.

The recent publication of the Trump administration’s new National Security Strategy showed that this decision was no accident. Unilateral disarmament is now official policy. Because—despite its name—this National Security Strategy is not really a strategy document. It is a suicide note. If the ideas within it are really used to shape policy, then U.S. influence in the world will rapidly disappear, and America’s ability to defend itself and its allies will diminish. The consequences will be economic as well as political, and they will be felt by all Americans.
