The overarching question imparting urgency to this exploration is: Can U.S.-Russian contention in cyberspace cause the two nuclear superpowers to stumble into war? In considering this question we were constantly reminded of recent comments by a prominent U.S. arms control expert: At least as dangerous as the risk of an actual cyberattack, he observed, is cyber operations’ “blurring of the line between peace and war.” Or, as Nye wrote, “in the cyber realm, the difference between a weapon and a non-weapon may come down to a single line of code, or simply the intent of a computer program’s user.”
Yet as this special report has pointed out, NATO is also deeply troubled. Douglas Lute and Nicholas Burns, two former American ambassadors to NATO, say Donald Trump has “hurtled the alliance into its most worrisome crisis in memory.” The report, “NATO at Seventy,” sets out a daunting array of the challenges it faces.
