Ryan Snyder and Benoît Pelopidas respond to Keir A. Lieber and Daryl G. Press's spring 2017 article, “The New Era of Counterforce: Technological Change and the Future of Nuclear Deterrence.”

The risks of nuclear escalation between the U.S. and China or Russia are greater than ever given the possibility of misinterpreted cyber espionage and military strikes against early warning systems. What can be done to reduce this risk?

The defining question about global order for this generation is whether China and the United States can escape Thucydides’s Trap. The Greek historian’s metaphor reminds us of the attendant dangers when a rising power rivals a ruling power—as Athens challenged Sparta in ancient Greece, or as Germany did Britain a century ago. Most such contests have ended badly, often for both nations, a team of mine at the Harvard Belfer Center for Science and International Affairs has concluded after analyzing the historical record. In 12 of 16 cases over the past 500 years, the result was war. When the parties avoided war, it required huge, painful adjustments in attitudes and actions on the part not just of the challenger but also the challenged.

Much of the immediate commentary on the Joint Comprehensive Plan of Action (JCPOA) signed between the P5+1 and Iran on July 14 focused on the deal’s details as well as its many shortcomings. Most of these reactions, both favoring and opposing the agreement, focused on elements of the nuclear package itself.

As the policy community prepares to assess an agreement between the U.S. and its P5+1 partners and Iran, Senate Foreign Relations Committee Chairman Bob Corker asked me to review the history of analogous agreements for lessons that illuminate the current challenge. In response to his assignment, I reviewed the seven decades of the nuclear era, during which the U.S. negotiated arms-control treaties, including the Non-Proliferation Treaty of 1968; strategic arms limitation talks and agreements from SALT to New Start; the North Korean accord of 1994; the agreements that helped eliminate nuclear weapons in Ukraine, Kazakhstan, and Belarus in the early 1990s; and the pact that eliminated the Libyan nuclear weapons program in 2003.

Among many lessons and clues from this instructive history, five stand out
