A look at the 50 countries that spend the most on their militaries

In the wake of World War II, 12 countries scattered throughout Europe and North America came together to form the North American Treaty Organization, a military alliance whose goal was to deter the Soviet Union from its conquest of Europe. It was founded on the principle of collective defense, which means that every member of NATO will come to the aid of any other member that is attacked. That's one reason why, for example, French and British troops fought in Iraq and Afghanistan after 9/11—and why NATO has not gotten involved in the Ukraine-Russia war.

This theory of collective defense requires collective spending so that every ally has a military that's fully prepared to help when called to do so. While it's almost universally agreed that some military spending is necessary for security purposes, especially given the ever-rising threats of terrorism around the world, it's still unclear how much defense spending is adequate.

Stacker ranked the 50 countries spending the most on their military, based on estimates from 2020 data (released in 2022) from the Stockholm International Peace Research Institute via The World Bank. The list provides a sweeping view of pressing conflicts around the world today.

It is often difficult to pinpoint what a country spends on its military in a given year. In 2002, NATO defined military expenditure to include current spending on the armed forces (including peacekeeping and paramilitary forces), defense ministries and other government agencies involved in defense, military space activities, personnel costs (pensions and social services), aid, research and development, operation and maintenance, and procurement of military supplies.

Despite that lengthy definition, however, coming up with an accurate calculation can be a formidable task. One country might consider certain costs to be military expenditures while another might classify the same expenses as another kind of spending. In addition, because some countries aren't transparent about their military budgets, the data experts put forth may not match the figures released by governments.

Still, getting even a general handle on which countries are spending the most on their militaries is helpful in discovering where hotspots are—from confrontations in the South China Sea to clashes between Russia and Ukraine to counter-terrorism operations in the Middle East—and identifying, for better or worse, the nations with the most firepower.

One important note— NATO itself has a military budget, which all 30 member states contribute to. For the 2022 fiscal year, that budget is set at a little over $1.74 billion.

The Global Peace Index in 2021 ranked New Zealand as the second most peaceful country in the world.

The accolade came even as the country’s defense budget reached highs it hadn’t touched since the Cold War days.

Compared with other countries, South Africa spends very little on its military despite having the 26th most powerful military in the world. It maintains a number of commitments, participating in UN peacekeeping missions across Africa while also being tasked with controlling pollution outbreaks and quashing crime within the country. It is considered one of the most well-trained and supplied militaries in Southern Africa despite analysts warning for years that it faces serious challenges and potential decline.

World War II ended in 1945, but Finland still subscribes to a theory of “total defense,” which requires the military be ready at all times for a large-scale emergency or conflict.

All Finnish men must serve up to a year in the armed forces or civil service. Increased aggression and threats from Russia in and around the Baltic region spurred Finland to increase the number of troops in its reserve, improve its international relations, and spend more on weapons and resources.

Despite its deceivingly low placement on this list, Egypt actually has one of the largest military forces and weapons catalogs in all of North Africa and the Middle East.

The armed forces are an essential part of the country’s infrastructure, bound up in everything from awarding government contracts to filling civilian markets with affordable goods. Because the military’s focus is primarily handling matters at home, it’s been ill-prepared for conflict until very recently when Russia and France stepped in to offer external training and support, bringing enlisted soldiers and leadership up to snuff should an international conflict arise.

Most of Chile's military spending goes toward UN peacekeeping missions and land disputes with Bolivia and Peru that go all the way back to the 19th century War of the Pacific. The land won by a victorious Chile cut off Bolivia's access to the sea and Bolivia has been fighting to get it back ever since. Though the International Court of Justice ruled against forcing Chile to negotiate with its neighbor for sea access, Bolivia has vowed to not stop fighting.

In 2014, Belgium and the other NATO members agreed to stop cutting defense spending and instead work to modernize their militaries. The Belgian government responded by proposing a 2018 plan to purchase $11.3 billion in new equipment and weapons systems in the next decade. However, Belgium has been making huge budget cuts in almost every other sector (including education and the judicial system), leading critics to question why the military should receive such a big boost while other government sectors are tightening their belts.

Romania previously sent troops to support NATO and U.S. efforts in Afghanistan and Iraq after 9/11. Since then the country has faced problems a bit closer to home, namely its location in the strategically important Black Sea region. Romania and Russia, the latter of which borders the Black Sea on the opposite side, have historically been at odds and Romania has positioned itself as a leader of its neighbors against Russian forces.

Romania in April 2022 came out in support of establishing new, permanent military bases to host American troops there in light of Russia's invasion of Ukraine.

When Russia stepped in and annexed Ukraine's Crimean Peninsula in 2014, the Ukrainian military found itself woefully unprepared for the fighting that followed. In the years since, Ukraine has stepped up its fighting force in both numbers and military capability without any significant increase in funding.

Russia invaded Ukraine on Feb. 24, which has galvanized a global response in support of Ukrainian troops and civilians. Efforts have included everything from arming and supporting Ukrainian soldiers to accepting Ukrainian refugees.

Oman's resources and location make it a high-security risk because ships carrying 20% of the world's oil pass through the Strait of Hormuz, which lies between Oman and Iran.

Iran has threatened to cut off access to the strait in the event of a conflict. Oman also hosts the U.S. during operations in the Middle East and assists in counter-terrorism operations. Thanks to its commitment to neutrality, Oman often mediates conflicts between the U.S. and Iran and other conflicting groups in the Middle East.

Kuwait, one of America's allies in the Persian Gulf, joined several other countries in fighting the Iranian-back Houthis fighting in nearby Yemen. But in most international situations, Kuwait prefers to mediate conflicts rather than make use of its military. Domestically, the Kuwaiti military is deeply concerned with border security; the shared border with Iraq leaves it potentially exposed to infiltration by ISIS and other extremist groups.

Since the 2003 Iraq War toppled Saddam Hussein's regime, victorious U.S. forces have tried mightily to train the Iraqi military so it is capable of taking on insurgent groups in the region, as well as helping to rebuild the nation. How successful that effort has been remains a question mark. It was only with the help of U.S.-backed forces that Iraq was able to reverse the juggernaut of the Islamic State (ISIS) and other extremist groups, finally declaring victory in 2017.

For five decades, the world's longest civil war was waged in Colombia, pitting left-wing guerilla groups against government-backed paramilitary forces. The war ended with a historic armistice agreement in early 2017, but Colombia has not stopped investing in its military.

A booming economy supported by oil and natural gas reserves led Algeria to become the largest military spender on the African continent, asserting its military dominance in the region. Algeria has managed to hold onto its #1 spot despite the country's recent economic downturn.

Much of the money is spent combating extremist groups, including Al-Qaeda in the Islamic Maghreb (AQIM), whose attacks have seen a marked decline thanks to Algerian defense efforts. Algeria is also in an arms race with other countries in North Africa (particularly Tunisia and Morocco).

Despite its small size, Singapore has one of the most advanced militaries in Southeast Asia. Its budget has remained steady in recent years despite cybersecurity threats and increased threats from terrorist organizations operating in the region, specifically ISIS and its affiliates. China's attempts to claim territory in the South China Sea are of concern to the nation-state, but the government has been careful not to let the conflict develop into outright hostilities.

The Dutch military shrank considerably in the years after the Cold War, apart from a small bump during the wars in Iraq and Afghanistan, thanks to routine budget cuts by the Dutch government. Although the country and its people continue to be strong supporters of the NATO alliance, which remains the cornerstone of its security policy, they are also committed to more defense in the European Union. The Netherlands has since realized it can't meet the security commitments to NATO under its current budget and has since slowly started ramping up spending.

Iran is unique in that it essentially has two militaries: a conventional armed forces, which is responsible for protecting the country’s borders and interests; and the Islamic Revolutionary Guard Corps, established in 1979  following the Iranian Revolution to protect the country’s Islamic republic political system.

In December 2021, the government announced it would be doubling the IRGC’s budget for the 2022 fiscal year, indicating increased interest in protecting the country’s political freedoms and ideologies. Generally speaking, Iran’s armies aren’t interested in offensive or peace-keeping missions, but rather focus all of their energy on ensuring its citizens are adhering to Islamic laws.

Because of its shared border, Turkey is heavily involved in Syria's long and devastating civil war and efforts to combat ISIS and other extremist groups in the Middle East. The military is also occupied with conflict within its borders, quashing repeated attempts by the Kurdish minority to establish its own state. A failed military coup in 2016 reestablished ties between the military and the government, changing the face of the armed forces as Turkey tries to increase its influence in the Middle East and Europe.

Australia seems likely to increase military spending to 2% of GDP by the early 2020s, a goal that firmed up its alliance with the U.S. The country also spent $1.3 billion to increase its share of the global arms trade, hoping to boost the Australian manufacturing industry.

Unlike most countries on this list, Italy has actively worked to decrease its defense spending in recent years. The populist government in 2019 announced plans to slash half a billion dollars from the military's budget in order to fund social programs. This puts the country's spending well below the NATO target of 2% of GDP and has drawn the ire of allies. Italy seeks to amend what counts as defense spending under NATO rules, arguing that cybersecurity should be included when calculating how much a nation is putting toward its defense.

Given South Korea’s volatile neighboring countries, it should come as no surprise that the republic spends so much on its military. Much of the country's military spending focuses on building up a stockpile of weapons (such as missiles, tactical communications systems, and rockets) that can be used as needed in response to direct action from other countries.

While South Korea's military spending has consistently grown in recent years, it is also facing a looming manpower shortage as its population has shrunk in the last several decades.

However, smaller-than-expected economic growth and domestic political conflict had an impact on Germany's ability to make good on the pledge.

The shifts in power and Saudi Arabia's leadership structure since 2015 led to a realignment of the country's priorities, evidenced by the Kingdom's military involvement in several conflicts in the Middle East in attempts to assert dominance in the region against regional enemy Iran.

Inside its borders, Saudi Arabia's military helps negotiate tensions between the Sunni and Shia Muslim sects and fight against extremist groups. The country's involvement in a devastating civil war in Yemen received worldwide attention and condemnation, especially following the assassination of journalist Jamal Khashoggi.

A stagnating Russian economy led to declines in military spending for the first time since the country defaulted on its debts in 1998. Russia's increased military spending reflects its willingness to become engaged in conflicts around the world.

The annexation of Ukraine's Crimean Peninsula in 2014 led to a military face-off with Ukraine, increasing tensions in the former Soviet-bloc, and worldwide condemnation. The country's late-February invasion of Ukraine and continued violence there has created turmoil throughout the region and calls to overthrow Putin or bring in NATO to end the conflict—even though doing so would likely invite World War III.

The rapidly modernizing military is hugely important to China's push to become the leading power in the Asian Pacific, dominate on the global stage, and disrupt U.S. military hegemony. Within the country, police and paramilitary forces have assisted the government in the forced internment of around 1 million Uighur Muslims, an ethnic minority within the country.

The U.S. spends far more on defense than any other country, with military spending accounting for around half of the federal budget. America is heavily involved in conflicts abroad and in the military support of its international allies, with some of its 1.3 million troops stationed across the Middle East and East Asia. This military spending has often been a subject of fierce political debate, with some U.S. lawmakers arguing that the country should cut back the Pentagon budget and limit involvement abroad, while others believe America should remain the world's 800-pound military gorilla.
