Russia’s Remaining Weapons Are Horrific and Confounding

| Mar. 23, 2022

Along with concerns over the possible deployment of tactical nuclear weapons, the Biden administration is now warning that the Russian military may launch a chemical weapons attack in Ukraine. Russia has used chemical weapons during past conflicts, notably in Chechnya and Syria, in violation of international law. Russian officials denied Biden’s accusation during a U.N. Security Council meeting Tuesday.

The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.

The Overwhelming Case for No First Use

| Jan. 13, 2020

The arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.

Iran and Weapons of Mass Destruction: The Military Dynamics of Non-Proliferation

| 2014

Weapons of mass destruction (WMDs) are not suitable for the Iranian Army, given its non-mechanized nature; its defensive military posture; its current status as a non-nuclear weapon state; and its sufficient conventional preparation to meet its protective security interests. This paper proposes three interlinked policy approaches to resolve the current impasse.

Space, Stability and Nuclear Strategy: Rethinking Missile Defense

| Forthcoming Summer 2010

"...[T]he United States has spent several tens of billions of dollars on missile defense research-and yet China, Iran, North Korea and possibly others have continued to pursue increasingly effective long-range ballistic capabilities. If missile defenses are a deterrent, why do US competitors-to say nothing of outright enemies-seem undeterred?"

The Viennese Connection: Engelbert Broda, Alan Nunn May and Atomic Espionage

| April 2009

Recently declassified materials have revealed the existence of a previously unknown network of Austrian communists in pre-war England. The group of young well-educated Viennese used unsuspecting social contacts and marriages of convenience to establish itself. Analysis of this network reveals some previously overlooked similarities between the 'Cambridge' spies Kim Philby and Alan Nunn May, as well as the emergence of a new nuclear spy, Engelbert Broda. Their wartime espionage as individuals took place at a time when non-communist British scientists were promoting the international sharing of atomic knowledge through unofficial channels. The newly released files reflect a characteristic preference of the British secret services for intelligence gathering rather than intervention and illustrate how vital leads follow from apparently trivial observations.

"...[T]here are plenty of laws that require or authorize sanctions against governments that knowingly provide direct support to proliferators. But these laws offer little protection against those governments that—through neglect, corruption, or incompetence—fail to keep the materials and technology needed to make nuclear, biological, and chemical weapons from slipping out of their control and across their borders."
