Can Europe Become a Nuclear Power?

Only if Europeans resume a serious debate about their responsibilities for their own security

“Do we need the bomb?” asked the front page of Welt am Sonntag, one of Germany’s biggest newspapers, last month. In an essay in the paper, political scientist Christian Hacke answered “yes”, arguing that, “for the first time since 1949, the Federal Republic of Germany is no longer under the United States’ nuclear umbrella.” » More

The Increasing Salience of 3D Printing for Nuclear Non-Proliferation

A growing number of defense-industrial 3D printing fairs, print-a-thons and the amount of defense dollars, particularly in the US, going into the technology of 3D printing speak to the fact that the defense industry and some countries’ armed forces recognize the great potential of the technology. 3D printing indeed allows the quicker, cheaper, and easier development of weapons, and even entirely new weapon designs. This applies to the full range of weapons categories: Small arms and light weapons (e.g. guns, guns, guns and grenade launchers), conventional weapon systems (drones, tanks, missiles, hypersonic scramjets) – and possibly even weapons of mass destruction.

3D printing, or additive manufacturing (AM), is increasingly adopted by various industries for rapid prototyping, the production of very complex objects in small numbers, and even the rapid production of end parts. Because of the features associated with 3D printing, particularly the high flexibility, the technology is, in a sense, the epitome of dual-use: One and the same 3D printer can produce both tools and weapons. A growing concern in the international security realm is that 3D printing could help a proliferating state in its quest for a secret nuclear weapons program.

A New Strategy toward North Korea: Proactive, Comprehensive, and Productive

This article was originally published by Pacific Forum CSIS on 21 April 2017.

The US has been contending with the challenge of the North Korean nuclear program for decades, yet we are no closer to the goal of convincing the North to abandon its nuclear ambitions. Indeed, that goal now appears unattainable under current circumstances.

Meanwhile the most serious threat facing the world today is the danger of nuclear proliferation. Both North Korea and Iran continue to develop nuclear weapons production capabilities. If they succeed, their regional neighbors will go nuclear in response, triggering a global cascade of proliferation. The resulting worldwide availability of nuclear weapons and fissile material to rogue states and terrorist groups will rapidly lead to a chaotic situation out of control.

The end goal of this strategy is a denuclearized Korean Peninsula, a North Korean economy that can sustain itself, a regional security environment free of military threats from North Korea, and decisive actions addressing the deplorable human rights situation throughout North Korea.

Rethinking the Apocalypse: Time for Bold Thinking on the 2nd Nuclear Age

This article was originally published by the War on the Rocks on 1 March 2016.

For much of the 46-year Cold War, many of the West’s most gifted strategists focused their talents on how to prevent the two nuclear superpowers from engaging in a war that could destroy them both — and perhaps the rest of the human race along with them. With the Soviet Union’s collapse in 1991, the threat of nuclear Armageddon receded dramatically and the First Nuclear Age drew to a close.

The world is far different today. On the one hand, both the United States and Russia have far smaller nuclear arsenals than they did at the Cold War’s end. The New Strategic Arms Reduction Treaty (START) limits each country to no more than 1,550 deployed strategic nuclear warheads. At the same time, new nuclear powers have emerged. These developments have introduced a shift from the bipolar Cold War nuclear competition, to an increasingly multipolar competition among nuclear powers and the onset of the Second Nuclear Age.

Yet this new age has not yet produced the foundational analyses that guided policymakers through the First Nuclear Age. Perhaps it is because the Second Nuclear Age appears so much more complex than the first. Or maybe it is because the Second Nuclear Age lacks the immediate existential danger posed by the Soviet Union. Or it might be that in the current age the best analytic talent has been devoted primarily to reducing the number of nuclear players (nonproliferation) and number of weapons (arms control and disarmament), rather than the consequences of such efforts falling short of success.
