Dating back to the first test in 1964, the Chinese nuclear force modernization process is motivated by other nuclear powers’ modernization across the years, mostly from the United States and the Soviet Union, but also by domestic factors such as economic debates and tensions in the scientific community.

Through multiple international initiatives, including the creation of the Arctic Council at the end of the Cold War in 1996, the Arctic appears to be one of the last areas of peaceful cooperation in the world. This “Arctic exception” is also devoid of any serious territorial dispute between the neighboring countries, some of which are nevertheless great powers: Russia, the United States, Canada, but also Sweden, Norway, Denmark (via Greenland), Iceland and Finland.

The topic of nuclear risk reduction has gained momentum in the international security debate among policymakers, nongovernmental organizations, and experts. 

Ever since nuclear weapons were developed by the United States and the Union of Socialist Soviet Republics, Europe has lived under the nuclear shadow. A major direct confrontation between “the West” and “the East” could have very likely resulted in the detonation of nuclear weapons on the continent. As the Cold War ended, massive reductions in the US and Soviet arsenals (from 70,300 in 1986 to 13,890 in 2019) and a new security architecture radically transformed the European security environment.

The instruments of cooperative security created during and since the Cold War to foster mutual confidence and reduce the risks of war, inadvertent escalation, and arms races, in and around Europe, have come under increasing strain.

Over the past few years, a debate on possible scenarios of limited nuclear weapons use has surfaced again in the United States. Russian nuclear saber-rattling since 2014 and the growing tensions in the Korean peninsula have led Washington to reassess its own ability to deter, or respond to, such a limited use of nuclear weapons.
