Who goes to war first?

In times of rising geopolitical tensions, the question of which country may initiate an armed conflict first is one that weighs heavily on the minds of policymakers and citizens alike. Using data-driven analysis and looking at key factors like military capabilities, defense spending, and past precedent can help provide clues as to which nations may be more likely to take aggressive action in potential flashpoints around the world.

How are countries ranked militarily?

When assessing which countries are militarily dominant and most capable of initiating armed conflict, experts look at composite measures of national power that take into account factors like total manpower, weapons capabilities, logistical abilities, and defense budgets. Organizations like Credit Suisse Research Institute and Global Firepower annually rank over 100 countries on their overall military strength using dozens of statistical metrics.

According to the 2022 military strength rankings index compiled by Global Firepower, the top 10 most powerful military forces in the world currently are:

Global Rank Country
1 United States
2 Russia
3 China
4 India
5 Japan
6 South Korea
7 France
8 United Kingdom
9 Turkey
10 Germany

The United States retains the top spot due to its huge budget, sophisticated weapons systems, extensive force projection capabilities, complex logistics networks, and technological advantages. However, rivals like China and Russia are rapidly modernizing their militaries and expanding their abilities to challenge American dominance.

Which countries spend the most on their militaries?

Looking at military expenditure as percentage of GDP provides insights into how much nations prioritize defense spending in their budgets. According to data from the Stockholm International Peace Research Institute (SIPRI), the countries that spent the largest share of their GDP on the military in 2021 were:

Country Military Expenditure as % of GDP
Oman 11.7%
Saudi Arabia 8.4%
Israel 5.6%
Algeria 5.3%
USA 3.5%
India 2.9%
China 1.7%
UK 2.2%
South Korea 2.8%
Russia 4.1%

However, in terms of total military spending, the United States outpaces all other nations by a large margin, spending over $800 billion in 2021. China and India have rapidly increased their defense budgets as well in recent years.

Which countries have initiated the most conflicts since World War 2?

Looking at involvement in armed conflicts provides insight into which nations use force to pursue foreign policy objectives. According to data analyzed by the Correlates of War project, the countries initiating the most conflicts since 1946 are:

Country Conflicts Initiated
USA 25
USSR/Russia 21
UK 12
Israel 12
North Korea 11
China 8
India 5
Egypt 4
Iran 4
Turkey 4

The data highlights how major powers like the US and Russia have repeatedly used military interventions, arms support, and shows of force to exert influence and pursue interests abroad. Regional powers like Israel and India have also initiated their share of conflicts with neighbors.

Key factors determining conflict initiation

While military capabilities provide the hard power needed for war, experts emphasize that economic, technological, and geopolitical dynamics also strongly influence which nations may initiate armed hostilities. Key factors include:

  • Global power shifts – Rising nations seeking regional dominance or declining powers fearing displacement are more aggressive.
  • Domestic politics – Leaders facing internal turmoil or desiring nationalistic surge often provoke external conflicts.
  • Regime type – Non-democracies are over 3 times more likely to initiate conflicts than democracies.
  • Arms races – Buildup of offensive weapons and escalatory cycles of mutual militarization fuel tensions.
  • Alliances – Alignment into rival blocs like NATO and Shanghai Cooperation Organisation fuels polarization.
  • Economic interdependence – Highly interconnected economies have reduced incentives for major war between nations.

Experts widely agree that the risk of a direct, large-scale conflict between great powers like the US, China, and Russia remains low due to nuclear deterrence and economic integration. However, brinkmanship, accidental clashes, and proxy conflicts remain ongoing threats. Sophisticated analysis must account for a wide array of factors to determine which nations are likely to initiate conflict escalation in potential geopolitical flashpoints.

Who is more likely to initiate war first in key regions?

Middle East

The tangle of conflicts and rivalries in the Middle East makes identifying specific potential aggressors complex. However, data points like Israel’s repeated interventions, Iranian support for militia groups, Turkey’s recent incursions into Syria, and Saudi Arabia’s war in Yemen highlight the region’s instability. Proxy conflicts and accidental clashes represent the largest risks.

Indo-Pacific

As the dominant regional military power, China’s increasing assertiveness in the South China Sea and threatening of Taiwan have raised concerns among Western analysts. However, most experts agree the US and its allies would likely initiate any direct clash, with China more inclined to salami-slicing tactics. North Korea remains the highest risk for sudden conflict initiation through limited military provocations.

Eastern Europe

Russia’s recent invasions of Georgia and Ukraine confirm its willingness to use direct military action against neighbors pursuing closer Western ties. Experts widely see Eastern Europe as the most likely site for a possible Russian-initiated conflict. However, NATO’s deterrent posture also risks accidental escalation during military buildups or standoffs.

Conclusion

In summary, a combination of military power, economic factors, alliance politics, and brinkmanship tactics determine which nations are more inclined to initiate armed conflicts. Sophisticated analysis shows the risks differ significantly by region. While deliberately initiated wars between major powers remain unlikely due to nuclear deterrence, miscalculations and proxy conflicts pose persistent threats. Maintaining robust multilateral institutions, open channels of communication, and regional balance of power are critical for reducing risks.
