A World on Edge: Why Global Tensions Are Rising and What History Can Tell Us

It is difficult to ignore the sense that the world feels unusually tense. News cycles are filled with military manoeuvres, diplomatic breakdowns, violent protests, and governments openly questioning long-standing alliances. From Eastern Europe to the Middle East, from East Asia to the Arctic, pressure points appear to be multiplying rather than calming.

While each conflict has its own local causes, taken together, they suggest something broader is happening. The current moment is not simply a collection of unrelated crises. It reflects bigger structural changes in global power, economics, and political trust.

The current conflict landscape

At present, several major armed conflicts are ongoing.

The war between Russia and Ukraine continues into its fourth year, with no comprehensive ceasefire in place. What began as a regional invasion has evolved into a grinding conflict that has reshaped European security, energy markets, and military planning across NATO.

In the Middle East, violence remains persistent. Fighting involving Israel, Gaza, and the West Bank continues alongside broader regional tensions that include Hezbollah, Iran, and proxy forces across Syria and Lebanon. In Syria itself, clashes involving Kurdish forces, government troops, and external actors have reignited instability in areas previously thought frozen.

Sudan remains locked in a devastating civil war between rival military factions, producing one of the world’s worst humanitarian crises. Myanmar’s civil conflict also continues, with the military junta facing resistance from ethnic armed groups and pro-democracy forces.

In Southeast Asia, border tensions between Thailand and Cambodia have flared, reminding observers that even regions often seen as stable are not immune to escalation. Meanwhile, long-standing tensions in the Taiwan Strait have intensified, with China conducting large-scale military exercises near Taiwan and diplomatic disputes growing sharper with Japan and the United States.

Alongside these wars are violent protests and internal unrest. Iran has faced waves of demonstrations driven by economic collapse, sanctions, and political repression. Haiti continues to struggle with armed gangs and institutional breakdown. Across parts of Africa’s Sahel region, insurgencies persist despite international intervention.

This is the global backdrop against which today’s anxieties are forming.

A shift away from the post-Cold War order

To understand why tensions feel so widespread, it helps to compare the present moment with earlier periods of instability.

After the end of the Cold War, much of the world entered a period often described as unipolar. The United States emerged as the dominant global power, international institutions expanded, and many conflicts were contained or managed through diplomacy and economic integration.

That period is ending.

Analysts increasingly describe today’s world as multipolar. Power is no longer concentrated in a single centre. China has risen as a strategic rival to the United States. Russia has sought to reassert influence through force. Regional powers such as Iran, Turkey, and Saudi Arabia are more willing to pursue independent agendas.

This resembles earlier periods of tension, particularly the years before the First World War and the late 1930s, when shifting power balances, economic strain, and weakened institutions created conditions for widespread conflict.

Economic pressure as a destabilising force

Another common thread linking today’s tensions is economic stress.

Global inflation, supply chain disruption, and energy insecurity have placed governments under pressure at home. When domestic stability weakens, foreign policy often becomes more assertive. Leaders seek to project strength externally to shore up authority internally.

Economic stress has played a similar role in past eras of instability. The Great Depression of the 1930s intensified nationalism and weakened cooperation. The oil shocks of the 1970s reshaped global politics and triggered regional conflicts.

Today’s pressures may not be identical, but the pattern is familiar.

Resource competition and strategic geography

Competition over resources and geography is also intensifying.

Control of energy routes, rare earth minerals, food supply chains, and strategic locations has become a priority for many governments. Greenland’s rising importance to the United States, China’s activity in the South China Sea, Russia’s Arctic expansion, and disputes over energy infrastructure all reflect this shift.

History shows that periods of rapid technological change often heighten resource competition. The Industrial Revolution drove imperial expansion. The oil age reshaped the Middle East. The digital and green energy transition is now doing something similar, placing new strategic value on minerals, data routes, and territory once considered marginal.

The role of the United States and global perception

Your observation about the United States is widely shared. For decades, the US positioned itself as a guarantor of global order. Its military presence was framed as stabilising, its alliances as protective.

In recent years, however, US actions have increasingly been viewed through a different lens. Military interventions, sanctions, and economic pressure have sometimes appeared unilateral rather than cooperative. Actions involving oil, shipping routes, or strategic assets have reinforced long-standing scepticism about American motives, particularly in parts of the Global South.

This does not mean the United States alone is responsible for global instability. Other powers are pursuing assertive policies of their own. But when the world’s most powerful state appears unpredictable or openly self-interested, it can lower the threshold for others to act aggressively.

In past eras, the decline or retreat of a dominant power has often coincided with rising conflict, as emerging powers test boundaries and regional disputes escalate without a clear arbiter.

Weakening trust in institutions and norms

Another critical factor is the erosion of trust in international institutions.

The United Nations, World Trade Organisation, and even regional bodies like the European Union are facing internal divisions and external challenges. Hungary’s open rejection of EU positions on migration, energy, and Ukraine is one example of how consensus is fracturing.

When rules feel optional and enforcement is uneven, states are more likely to act unilaterally. This dynamic has appeared before. The League of Nations struggled to restrain aggression in the 1930s. Its failure did not cause war on its own, but it removed barriers that might have slowed escalation.

Patterns across history

Looking across history, periods of heightened global tension tend to share several features.

Power is shifting rather than settled. Economic systems are under strain. New technologies are changing how wars are fought and how influence is exercised. Institutions designed for an earlier era struggle to adapt. Public trust in leadership declines, while nationalism rises.

The current moment fits this pattern uncomfortably well.

That does not mean global war is inevitable. History also shows that recognition of danger can lead to reform, diplomacy, and restraint. The Cuban Missile Crisis, for example, occurred at the peak of Cold War tension but ultimately produced new arms control agreements.

What to take from this moment

The world today is not falling apart, but it is clearly unsettled. The number of conflicts and flashpoints reflects a system under strain rather than a sudden collapse of order.

Understanding this context matters. It helps explain why tensions feel omnipresent, why conflicts echo one another, and why public scepticism toward power is growing. It also reminds us that instability is not permanent. Past eras of tension eventually gave way to new arrangements, often shaped by hard lessons.

Whether the current moment leads to escalation or recalibration will depend on how governments respond to pressure, whether cooperation can be rebuilt, and whether history’s warnings are taken seriously rather than ignored.

The pattern is clear. What remains uncertain is how the world chooses to break it.
