Abstract:
The prospects for nuclear arms control appear dim following Russia’s invasion of Ukraine. Instead of continued reliance on nuclear deterrence, the resulting new awareness of nuclear risks should inform bold nuclear disarmament measures in the long term. Drawing on previous debates on ‘minimal nuclear deterrence’, this paper argues that nuclear deterrence is possible at low numbers, and hence reliance on nuclear deterrence is not an obstacle to significant progress in nuclear disarmament. In particular, there is scope for reducing the vast Russian and United States nuclear arsenals, which risk planetary-scale destruction and stand in the way of multilateral nuclear disarmament. At the same time, recent military-technological evolution has raised the bar for minimal nuclear deterrence by questioning the survivability of nuclear forces. In addition to making recommendations on how to address such strategic challenges, the paper addresses some conceptual dilemmas traditionally associated with minimal nuclear deterrence.

Abstract:
World military expenditure in 2020 is estimated to have been $1981 billion, the highest level since 1988—the earliest year for which SIPRI has a consistent estimate for total global military spending. World military expenditure in 2020 was 2.6 per cent higher in real terms than in 2019 and 9.3 per cent higher than in 2011. The global military burden—world military expenditure as a share of global gross domestic product—rose by 0.2 percentage points in 2020, to 2.4 per cent. This increase was largely due to the fact that most countries in the world experienced severe economic downturns in 2020 related to the Covid-19 pandemic, while military expenditure continued to rise overall. This Fact Sheet highlights the regional and national military expenditure data for 2020 and trends over the decade 2011–20. The data is from the updated open-access SIPRI Military Expenditure Database, which provides military spending data by country for the years 1949–2020.

Abstract:
Even though the volumes of arms exported by emerging suppliers are lower than those of the established exporters, they can nonetheless have a direct impact on international and regional security. The diversification in global arms transfers caused by the emergence of new suppliers therefore deserves scrutiny. Brazil, South Korea, Turkey and the United Arab Emirates are examples of emerging suppliers. Despite a continuous reliance on foreign technologies, they have managed to establish themselves in several niche categories of armaments or, in the case of South Korea, to widen the types of arms that they export. Exports of these emerging suppliers tend to go primarily to Africa, Asia and the Middle East, where most active armed conflicts are located, and also to Latin America. However, the drivers of the four countries’ arms exports differ: some have supplied with the intent to gain political influence, while others have primarily focused on the economic benefits.

Abstract:
The volume of international transfers of major arms in 2016–20 was 0.5 per cent lower than in 2011–15 and 12 per cent higher than in 2006–10. The five largest arms exporters in 2016–20 were the United States, Russia, France, Germany and China. The five largest arms importers were Saudi Arabia, India, Egypt, Australia and China. Between 2011–15 and 2016–20 there were increases in arms transfers to the Middle East and to Europe, while there were decreases in the transfers to Africa, the Americas, and Asia and Oceania. From 15 March 2021 SIPRI’s open-access Arms Transfers Database includes updated data on transfers of major arms for 1950–2020, which replaces all previous data on arms transfers published by SIPRI. Based on the new data, this Fact Sheet presents global trends in arms exports and arms imports, and highlights selected issues related to transfers of major arms.
