Russia’s Dual Assault: How Brussels, Washington, and Beijing Helped Moscow to Undermine the Non-Proliferation Regime
The “Ukraine crisis” concerns more than lofty European values, Ukrainian humanitarian issues, or abstract international law. Russia’s attack on Ukraine is also an assault on the world’s nuclear nonproliferation regime. It subverts the logic of the 1968 Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Given its purpose of curtailing the spread of weapons of mass destruction, namely nuclear missiles and atomic bombs, the NPT is one of the most important international accords in human history. » More
NATO’s missile defense program remains mired in controversy because of its disputed costs, feasibility and strategic necessity, and because of how it has negatively impacted the Alliance’s relations with Russia. To discuss these and related issues, ETH Zurich’s Center for Security Studies (CSS) recently hosted an Evening Talk on the future of NATO missile defense. The guest speakers were Roberto Zadra, who heads the Ballistic Missile Defense Section in NATO’s Defense Investment Division, and Bruno Rösli, who is the Deputy Director of Security Policy for the Swiss Federal Department of Defense, Civil Protection and Sport. » More

On a cold winter day in the middle of October, I flew into Tallinn, the capital of Estonia. From there I would travel exclusively by bus from Tallinn on the Baltic Sea to Tartu in southern Estonia, then on to Riga, Latvia, and finally to Vilnius in southern Lithuania. » More
The most basic definition of a security community of independent states within a defined region is that there exists a reliable expectation that the states within that region will not resort to war to prosecute their disputes. Put another way, such a “pluralistic security community … [is] a transnational region comprised of sovereign states whose people maintain dependable expectations of peaceful change’.” 1 That is certainly a widely affirmed expectation, even if not yet a guarantee, for the Arctic region.
But there is another characteristic of a security community that is less entrenched in the Arctic, namely, “the absence of a competitive military build-up or arms race involving [its] members.”2 There is no denying that there is currently a build-up of conventional military capacity within the region,3 and it is not yet definitively clear whether it will turn out to be a competitive build-up that undermines the growing expectation that change will be peaceful, or whether it will instead facilitate increased security cooperation and build capacity for more effective domestic and cross border support to civil authorities in search and rescue, and in monitoring regional activity and ensuring compliance with international regulations. » More
