As global tensions continue to escalate in 2025, the question of potential large-scale conflicts weighs heavily on many minds. According to recent YouGov polling, between 41% and 55% of people in major European countries think that another world war is likely to occur within the next 5-10 years. These concerns have been dramatically heightened by the June 21, 2025 U.S. airstrikes on Iran's nuclear facilities, marking a major escalation in Middle East tensions.
With Russian President Vladimir Putin himself expressing worry about the world heading towards World War Three, and the 2025 Doomsday Clock warning of increased nuclear risks, understanding current geopolitical tensions has never been more critical. This comprehensive analysis examines the complex web of international relations, potential flashpoints, and expert opinions on global conflict scenarios. Rather than fear-mongering about destruction, we'll focus on understanding the dynamics at play and exploring pathways to peace.

Breaking: U.S. Strikes on Iran's Nuclear Facilities
On June 21, 2025, the United States conducted major airstrikes on Iran's nuclear infrastructure, marking the most significant escalation in the Middle East since the Gaza conflict began. President Trump announced that U.S. forces struck Iran's three main nuclear sites, including:
- Fordow facility: Hit with six bunker-buster bombs from B-2 bombers
- Additional sites: Targeted with 30 Tomahawk missiles
- Isfahan: Explosions reported near Iran's largest nuclear research complex
UN Secretary-General Antonio Guterres called the strikes a "dangerous escalation in a region already on the edge – and a direct threat to international peace and security." This development dramatically increases the risk of wider regional conflict and potential global involvement.
What Countries Will Be Destroyed in World War 3?
The question of which countries would face destruction in a hypothetical World War 3 is both deeply concerning and inherently speculative. Russian President Vladimir Putin himself expressed worry when asked if the world was heading towards World War Three, highlighting how even global leaders recognize the gravity of current tensions.
Rather than making predictions about destruction, experts focus on understanding vulnerability factors and potential conflict scenarios. Retired military officials and defense policy experts suggest that any major war would likely result from tensions between five major players: Russia, China, North Korea, Iran, and the United States.
Major Flashpoints and Vulnerable Regions
Eastern Europe: The Russia-Ukraine Nexus
The war in Ukraine has brought widespread devastation, with key regions reduced to rubble and thousands of lives lost. The conflict has already demonstrated how modern warfare can devastate entire regions:
- Ukraine: Currently experiencing the most direct impact of major power conflict
- Poland: Polish Prime Minister Donald Tusk warned of a "real risk" of war
- Baltic States: NATO's eastern frontier faces increased vulnerability
- Belarus: Already drawn into the conflict as Russia's ally
NATO Secretary-General Mark Rutte warned that "Russia could be ready to use military force against NATO within five years", emphasizing the ongoing risk to Eastern European nations.
Middle East: A Powder Keg Ignited
The ongoing conflict between Israel and Palestine has raised stakes in the Middle East to dangerous levels, with the amount of bombs dropped on Gaza officially surpassing World War II levels at approximately 70,000 tons since October 7, 2023.
Breaking Development - June 21, 2025
The United States has dramatically escalated tensions by conducting airstrikes on Iran's three main nuclear sites. President Trump announced that six bunker-buster bombs were dropped on Fordow, with 30 Tomahawk missiles fired against other nuclear sites, declaring "Fordow is gone." UN Secretary-General Antonio Guterres called the strikes a "dangerous escalation in a region already on the edge".
Countries at highest risk include:
- Iran: Now directly attacked by the U.S., facing potential retaliation scenarios
- Israel and Palestine: Already engaged in active conflict
- Lebanon: Hezbollah's presence creates vulnerability
- Syria and Yemen: Ongoing proxy conflicts
- Gulf States: Risk of oil infrastructure targeting and economic disruption
Asia-Pacific: The Taiwan Question
Beijing sees Taiwan as an integral part of unified Chinese territory, creating one of the world's most dangerous potential flashpoints:
- Taiwan: 47% of survey respondents predicted the world will largely be divided into China-aligned and US-aligned blocs by 2035
- South Korea: Faces threats from North Korea
- Japan: Would likely be drawn into any regional conflict
- Philippines: Territorial disputes in South China Sea
The Nuclear Dimension
Recent assessments paint an alarming picture of nuclear risks. According to the 2025 SIPRI Yearbook, "a dangerous new nuclear arms race is emerging at a time when arms control regimes are severely weakened."
Key nuclear developments:
- 48% of experts expect nuclear weapons to be used in the next decade (Atlantic Council survey)
- 88% expect at least one new country to obtain nuclear weapons by 2035
- China's arsenal growing by ~100 warheads annually, now exceeding 600 total
- Russia lowered its nuclear use threshold in 2024, putting forces on full combat alert
- U.S.-Russia arms control near collapse with New START expiring in 2026
The 2025 Doomsday Clock statement warns that "longstanding concerns continued or were amplified in 2024," noting the U.S. has embarked on the world's most expensive nuclear modernization program while China may now be deploying warheads on missiles during peacetime.
Carnegie Endowment experts note that NATO-Russia tensions emerged as the geopolitical hotspot most likely to trigger a nuclear exchange, while the Federation of American Scientists warns the nuclear landscape is "far more complicated and, in many ways, more precarious than during the Cold War."
Economic and Social Vulnerabilities
Beyond military targets, modern conflicts would devastate:
Economic Centers
- Major financial hubs (New York, London, Shanghai, Tokyo)
- Critical infrastructure and supply chain nodes
- Energy production facilities
- Technology manufacturing centers
Humanitarian Impact
Using the fictional scenario from 2027-2035, analysts suggest over 300 million casualties in a full-scale global conflict, though this remains purely speculative.
Expert Perspectives on Conflict Prevention
Despite rising tensions, most experts agree that a full-scale world war is still unlikely—but not impossible. Key preventive factors include:
- Economic Interdependence: Economies are deeply interlinked, and nuclear deterrence still plays a powerful role
- Diplomatic Channels: Continuous dialogue prevents misunderstandings
- International Institutions: UN, NATO, ASEAN provide frameworks for conflict resolution
- Public Opposition: Global populations largely oppose military escalation
Different Scenarios and Alliance Structures
Experts suggest various alliance configurations could emerge:
Western Alliance
- United States and NATO members
- Asia-Pacific partners (Japan, South Korea, Australia)
- Democratic nations globally
Eastern Bloc
- Nearly 60% expected the China-aligned bloc to include Russia, Iran, and North Korea as formal allies
- 46% of survey respondents agreed that the emerging axis of Russia, Iran, China, and North Korea will be formal allies by 2035
Neutral/Non-Aligned Nations
Many countries would likely attempt to remain neutral, following historical precedents from previous world wars.
Historical Context and Lessons
Understanding past conflicts provides crucial insights:
- World War I: Showed how alliance systems can escalate regional conflicts globally
- World War II: Demonstrated unprecedented destruction with 50-80 million casualties
- Cold War: Proved that nuclear deterrence can prevent direct confrontation
The question of why conflicts start remains crucial for prevention efforts.

- Psychological Resilience: Mental health support systems
FAQs
Is World War 3 inevitable?
Most experts agree that a full-scale world war is still unlikely—but not impossible. Military analysts point out that global powers have more to lose than to gain from direct confrontation.
Which countries are most at risk in a global conflict?
Countries along major fault lines face the highest risks: Ukraine and Eastern European NATO members, Taiwan and neighboring Asian nations, and Middle Eastern countries involved in current conflicts. Historical analysis suggests that nations between major powers often suffer most.
How likely is nuclear weapon use in World War 3?
Almost six in ten Britons (59%) think it is likely that nuclear weapons would be launched in a third world war, making nuclear deterrence and arms control critically important.
What are the main triggers for World War 3?
Experts cite Russia's actions in Europe, China's ambitions regarding Taiwan, Iran's nuclear program, and North Korea's unpredictability as primary risk factors.
Can World War 3 be prevented?
Yes, through diplomacy and dialogue between nations, economic cooperation and interdependence, strengthened international institutions, and investment in education and cultural exchange programs.
What would be the economic impact of World War 3?
Based on World War II's impact (approximately $4 trillion in today's terms), a modern global conflict would likely cause unprecedented economic devastation due to interconnected global supply chains and financial systems.
Are we currently in the early stages of World War 3?
While some analysts debate whether current conflicts represent early stages, most experts view them as separate regional conflicts rather than a unified global war.
How many people could die in World War 3?
Speculative scenarios suggest casualties could exceed 300 million, though significant percentages believe it could result in the deaths of most people in the world if nuclear weapons are used extensively.
Conclusion
While the question "what countries will be destroyed in World War 3?" reflects genuine concerns about global tensions, focusing solely on destruction scenarios can be counterproductive. The highest likelihood outcome for world order in the decade ahead would not be a unipolar order or bipolar Cold War-style competition, but loose multipolarity.
Rather than dwelling on apocalyptic scenarios, we must channel our concerns into constructive action. Understanding the complexities of modern geopolitics, supporting diplomatic solutions, and building resilient communities offer better paths forward than fear-based speculation.
The lessons from history remind us that even after devastating conflicts, humanity can rebuild and create institutions designed to prevent future wars. Our energy is better spent working toward that goal than imagining destruction.
As we navigate these turbulent times, remember that every individual can contribute to peace through informed citizenship, cross-cultural understanding, and support for diplomatic solutions. The future remains unwritten, and our collective choices today will determine whether we face conflict or cooperation tomorrow.
