As a share of gross domestic product (GDP), Ukraine spent more on its military than any other country in 2023, reaching 37 percent of the country's GDP. The high figure is due to the country being invaded by Russia in February 2022. Algeria and Saudi Arabia followed behind.Leading military spending countriesIn gross terms, the countries with the highest military spending are the United States, China, and Russia. However, these are countries with large populations and GDPs, and smaller countries usually cannot compete alone, regardless of how much they invest. For this reason, they form alliances such as the North Atlantic Treaty Organization (NATO). NATO countries aim to pool two percent of their GDP towards their own militaries and to aid each other in case of war. Regional differencesThe past decade has seen an increase in global military spending. This has not been distributed evenly. That period saw large positive changes in military spending from several Asian countries, including a large increase from China. While this does not reflect the number of active conflicts, it reflects growing tensions in global affairs.

The average for 2022 based on 145 countries was 1.98 percent. The highest value was in Ukraine: 33.55 percent and the lowest value was in Haiti: 0.07 percent. The indicator is available from 1960 to 2022. Below is a chart for all countries where data are available.

In 2024, Poland's defense spending as a share of gross domestic product was **** percent, the highest of all NATO member states, followed by Estonia at **** percent, and then the United States at **** percent. It is a target of NATO that every member country should spend at least two percent of their GDP on defense. As of this year, it is estimated that all but eight of the alliance's 31 member states were meeting this target. The average expenditure on defense expenditure across all NATO member states was **** percent in 2024, compared with **** percent in the previous year. NATO, Trump, and the War in Ukraine Russia's full-scale invasion of Ukraine in February 2022 shook many European powers out of a creeping complacency that had set in since the end of the Cold War. It led directly to the applications of Sweden and Finland to the alliance in 2022, with the latter joining later that year. The conflict has however also underlined how Europe's security is still underpinned by American military power, with the United States the main contributor of military aid to Ukraine. Furthermore, in overall defense spending, the U.S. spends far more than the rest of NATO combined. The current Trump administration has frequently criticized NATO states that they see as taking advantage of this discrepancy, urging other members to reach and even exceed the two percent threshold. Article 5 triggered in the aftermath of 9/11 While NATO was founded with the aim of deterring the Soviet Union in the Cold War, its central defense clause "Article 5" whereby an attack on one member is considered an attack on all, has only been triggered once; after the 9/11 terrorist attacks on the United States. NATO's involvement in the subsequent War in Afghanistan was a direct result of this, with troops supporting the operation from across the alliance. Although NATO's focus drifted towards counter-insurgency, and the threat from terrorism in this period, its original purpose has become far more important recently.

The United States led the ranking of the countries with the highest military spending in 2023, with 916 billion U.S. dollars dedicated to the military. That constituted over 40 percent of the total military spending worldwide that year, which amounted to 2.4 trillion U.S. dollars. This amounted to 3.5 percent of the U.S. gross domestic product (GDP), placing the U.S. lower in the ranking of military expenditure as a percentage of GDP than for instance Saudi Arabia, Israel, Algeria, and Russia. China was the second largest military spender with an estimated 296 billion U.S. dollars spent, with Russia following in third. Defense budgetAccording to the U.S. Congressional Budget Office, the outlays for defense will rise to 1.1 trillion U.S. dollars by 2033. The largest parts of the budget are dedicated to the Departments of the Navy and the Air Force. The budget for the U.S. Air Force for 2024 was nearly 260 billion U.S. dollars.Global military spendingThe value of military spending globally has grown steadily in the past years and reached 2.44 trillion U.S. dollars in 2023. Reasons for this are the outbreak of the Russia-Ukraine war in 2022, the war in Gaza, as well as increasing tensions in the South China Sea. North America is by far the leading region worldwide in terms of expenditure on the military.

In 2023, the military expenditure of Colombia accounted for approximately 2.87 percent of the country's gross domestic product (GDP), the highest share in Latin America and the Caribbean. Ecuador is also one of the countries in the region with the highest military budget in relation to its GDP, having spent an estimated sum comparable to 2.3 percent of its GDP on military expenditures.
