But developing, exporting, and deploying military personnel and weaponry costs nations hundreds of billions every year. In 2021, global military spending reached $2.1 trillion, rising for its seventh year in a row. Using data from the Stockholm International Peace Research Institute (SIPRI), this visualization shows which countries spent the most on their military in 2021, along with their overall share of global military spending.

Which Countries Spend the Most on Military?

The United States was the top nation in terms of military expenditure, spending $801 billion to make up almost 38% of global military spending in 2021. America has been the top military spending nation since SIPRI began tracking in 1949, making up more than 30% of the world’s military spending for the last two decades. U.S. military spending increased year-over-year by $22.3 billion, and the country’s total for 2021 was more than every other country in the top 10 combined. The next top military spender in 2021 was China, which spent $293.4 billion and made up nearly 14% of global military spend. While China’s expenditure is still less than half of America’s, the country has increased its military spending for 27 years in a row. In fact, China has the largest total of active military personnel, and the country’s military spending has more than doubled over the last decade. While Russia was only the fifth top nation by military spending at $65.9 billion in 2021, it was among the higher ranking nations in terms of military spending as a share of GDP. Russia military expenditures amounted to 4.1% of its GDP, and among the top 10 spending nations, was only beaten by Saudi Arabia whose spending was 6.6% of its GDP.

Military Collaboration Since the Russia-Ukraine Conflict

Russia’s invasion of Ukraine in February has resulted in seismic geopolitical shifts, kicking off a cascade of international military shipments and collaboration between nations. The security assistance just sent by the U.S. to Ukraine has totaled $8.2 billion since the start of the war, and has shown how alliances can help make up for some domestic military spending in times of conflict. Similarly, Russia and China have deepened their relationship, sharing military intelligence and technology along with beginning joint military exercises at the end of August, alongside other nations like India, Belarus, Mongolia, and Tajikistan. Since China’s breakthrough in hypersonic missile flight a year ago, Russia has now been testing its own versions of the technology, with Putin mentioning Russia’s readiness to export weaponry he described as, “years, or maybe even decades ahead of their foreign counterparts”.

Sanctions and Energy Exports: New Weapons in Modern Warfare

Along with advanced weaponry, sanctions and energy commodities have become new tools of modern cold warfare. As Western economic sanctions attempted to cripple Russia’s economy following its invasion, Russian gas and oil supplies have been limited and forced to be paid in rubles in retaliation.
Global trade has been turned into a new battlefield with offshore assets and import dependencies as the attack vectors. Along with these, cyberattacks and cybersecurity are an increasingly complex, obscure, and important part of national military and security. Whether or not Russia’s invasion of Ukraine ends in 2022, the rise in geopolitical tensions and conflict this year will almost certainly result in a global increase in military spending. on After a year of casualties, structural devastation, and innumerable headlines, the conflict drags on. Many report the impacts to the economy, social demographics, and international relationships, but how do science and academia fair in the throes of war? Within the actions and responses of the conflict, we take a look at how six key scenarios globally shape science.

War’s Material Impacts to Science

1. Russia Invades Ukraine

The assault to research infrastructure in Ukraine is devastating. Approximately 27% of buildings are damaged or destroyed. The country’s leading scientific research centers, like the Kharkiv Institute of Physics and Technology, or the world’s largest decameter-wavelength radio telescope, are in ruins. While the majority of research centers remain standing, many are not operating. Amidst rolling blackouts and disruptions, a dramatic decrease in research funds (as large as 50%) has cut back scientific activity in the country. Rebuilding efforts are underway, but the extent to which it will return to its former capacity remains to be seen.

2. Ukraine Fights Back

As research funds have been redirected to the military, and scientists, too, have pivoted in a similar way. Martial law and general mobilization have enlisted male researchers, especially those with military experience and those within the 18-60 age range. Women were exempt until July 2022. Those with degrees in chemistry, biology, and telecommunications were required to enter the military registry. For both men and women researchers alike, these requirements meant staying in the country for the remainder of the year. Extensions for mobilization have subsided as of February 19th, 2023.

Social Impacts of War to Science

3. Western Leaders Exclude Russia

One year ago, scientists and institutions around the world immediately launched into protest against Russia’s escalation:

The European Commission agreed to cease payments to Russian participants and to not renew contract agreements for Horizon Europe The $300-million, MIT-led Skoltech program was dissolved one day after the war began, with no foreseeable restart in the future Various governments and research councils in the European Union froze collaborations and discouraged working with Russian institutions The European Organization for Nuclear Research, CERN, barred all Russian observers and will dismiss almost 8% of its workers—about 1,000 Russian scientists—hen contracts expire later this year

These condemnations, and more, remain in effect today and are emboldened by what has come to be known as a “scientific boycott”. Journal publishers around the world imposed some of their own sanctions on Russian institutions and scientists in light of this boycott. These range from prohibiting Russian manuscript submissions (Elsevier’s Journal of Molecular Structure) to scrubbing journal indices of Russian papers and authors.

4. Russia Dissociates from the West

As a response to the sanctions imposed on the Russian economy, Russia ceases to sell natural gas to most of Europe. Institutions are reassessing their usage and dependence on Russian energy, but alternatives are not yet affordable. The German Electron Synchrotron (DESY) in Hamburg, home to the world’s most powerful X-ray laser, is struggling with rising electricity costs. CERN, for instance, has already cut its data collection for the year by two weeks in order to save money. This makes it difficult for pre-war projects to continue collaborating with Russia. As a result, there are questions about how withdrawals may be affecting Russian science, too. For now, that remains relatively unknown, though some have guesses. Young scientists, many barred from attending international conferences and meetings, may seek employment or opportunity elsewhere to develop their careers. Some speculate a “brain drain” effect may occur, similar to the academic fallout of the Soviet Union’s collapse in the 1990s. How Russia will participate in pre-war international research collaborations is still unknown. For now, a number of pre-war projects ranging from the Arctic to the fire-prone wilds of northern Russia are on hold. All of these scenarios paint a concerning picture about the progress of research. There are indications that Russian scientific collaboration may already be shifting eastward.

Philanthropic Impacts of War to Science

5. New Homes for Ukrainian Science

Finding support for Ukrainians emigrating from the conflict is difficult, but not impossible. Though many Ukrainians scientists remain in the country making the best of a difficult situation, approximately 6,000 are now living abroad. Most Ukrainian emigrants are now living in Poland and Germany. Some scientists continue to work remotely, supporting projects at their home institutions or with new research programs they’ve found since relocating. These success stories are thanks to the work of a number of ad-hoc mobilizations that help keep researchers working in the European cooperation. Groups like MSC4Ukraine help postdoc students and researchers find new opportunities across Europe. Social media trends like #Science4Ukraine help connect researchers to other supportive movements.

6. The International Rebuilding of Ukrainian Science

Various research institutions have also lent support to the survival and rebuilding of science in Ukraine:

The largest science prize, the Breakthrough Prize, recently donated $3 million to fund research programs and reconstruction efforts Federal research councils, like those in Netherlands and Switzerland, also have programs to formally support displaced scientists and researchers The European Union is investigating new funding schemes that could repurpose almost €320 billion of frozen Russian Federal Reserves

No Consensus on Boycott

While the Western front seems united in it’s condemnation of the war, the international science community isn’t in total agreement with a science boycott. Some scientists argue that excluding Russian scientists—especially those who have vocalized their disdain for the war—serves to punish unrelated individuals. This fractures the benefits of international scientific exchange. Others, especially those in countries who are economically dependent on Russia, have remained silent or even supported the invasion. In these cases, Russia’s science initiatives may lean more heavily in their direction. It’s easy to appreciate how war complicates many different angles of the global research ecosystem. After one year, how things will turn out remains a mystery. But one thing is for certain: science adapts and progresses even in the bleakest times. For now, supporting all efforts to reduce conflict remains in science’s best interests. Full sources here
