Military Cooperation

This SIPRI Insights seeks to contribute to the operationalization of nuclear disarmament verification. It explores existing solutions to define a baseline for new arms control and disarmament verification regimes, and considers the requirements for verification under the 2017 Treaty on the Prohibition of Nuclear Weapons (TPNW). Existing solutions might be sufficient to enable several near-term disarmament steps and to lay the foundations for a comprehensive nuclear disarmament verification regime supporting the TPNW. However, more technical work is needed to achieve all the preconditions for a nuclear weapon-free world, particularly on verifying the dismantlement of nuclear weapons. At the same time, a more favourable political context could reduce the extent to which technical challenges are perceived as obstacles to nuclear disarmament. Even in the absence of new disarmament treaties, the operationalization of disarmament verification can begin at a conceptual and discursive level, by adopting a more policy-oriented approach to disarmament verification.

Europe’s security environment has deteriorated in the last few years. New threats include a more aggressive Russia, instability in Eastern Europe, the Middle East, and Africa, and cyberthreats from hostile governments and nonstate actors.
The United States is sending mixed signals about continuing the high level of military support it has provided for Europe in the past decades.
Adding to the challenge, Europe’s defense capabilities have declined. Equipment inventories have been reduced to critical levels across most weapons categories, and many systems are outdated. Austerity and an increase in missions abroad have reduced the readiness of Europe’s forces; in many countries, up to half of military equipment, from infantry vehicles to helicopters, is not available at any one time.
Europe’s fragmented approach to defense exacerbates the situation: Europe has six times more types of major weapon systems than the US. In many European defense projects, countries put the interests of their national industries ahead of European capability building, military cooperation, and interoperability.
