The simultaneous escalation of the U.S.–Israel war against Iran and Washington’s growing pressure on Europe over Greenland has placed the European Union in one of the most complex strategic dilemmas since the end of the Cold War. On one side, the United States—Europe’s long-standing security guarantor—expects European support in its confrontation with Iran. On the other side, Washington’s aggressive posture regarding Greenland has shaken European confidence in the transatlantic alliance.

This unprecedented situation raises a critical question: Should Europe support the United States in its war against Iran when Washington itself is threatening the sovereignty of a European territory?

The issue goes far beyond a regional conflict in the Middle East. It touches the future of NATO, the rules-based international order, Europe’s strategic autonomy, and the balance of global power.

The Expanding US–Israel War Against Iran

A Conflict With Global Consequences

The war between the United States, Israel, and Iran has rapidly escalated into one of the most dangerous geopolitical crises of the decade. Airstrikes, missile attacks, and proxy conflicts have spread across several countries, including Lebanon, Iraq, and the Persian Gulf.

Recent reports indicate that the conflict has already caused over 1,800 deaths across Iran, Lebanon, and Israel, while more than 140 U.S. service members have been wounded. Iran has responded with drone and naval attacks and has threatened to disrupt oil shipments through the Strait of Hormuz, a chokepoint for global energy supplies.

This escalation has triggered global economic and security concerns:

• Oil prices have surged due to threats to Gulf shipping routes.

• International energy markets are under severe stress.

• Refugee movements and regional instability are growing.

For Europe, the war carries additional risks. Security agencies warn that the conflict could trigger terrorism threats, cyberattacks, and extremist violence on European soil.

Europe’s Divided Response to the Iran War

Strategic Dependence vs Political Autonomy

The European Union has struggled to form a unified response to the war. Some governments lean toward supporting the United States, while others emphasize diplomacy and international law.

Italy’s Prime Minister Giorgia Meloni, for instance, recently criticized the U.S.–Israeli campaign as part of a dangerous trend of unilateral interventions, even while acknowledging the security threat posed by Iran’s nuclear ambitions.

This division reflects deeper structural tensions within Europe:

• Eastern European states generally support strong alignment with Washington.

• Southern European governments fear economic and migration consequences.

• Western European powers increasingly advocate strategic independence.

Analysts describe the EU’s reaction as fragmented and geopolitically weak, warning that the bloc risks becoming “paralysed” in the face of major global crises.

The Greenland Crisis: Why Europe Distrusts Washington

Trump’s Threats Against Denmark

At the same time that Washington is demanding support against Iran, it has created a major diplomatic crisis with Europe over Greenland, a semi-autonomous territory belonging to Denmark.

The U.S. administration has repeatedly expressed interest in acquiring the island and has even refused to rule out military force to obtain it.

Washington has also threatened economic retaliation, including tariffs on European countries that oppose its plans.

European leaders reacted strongly:

• The EU declared full solidarity with Denmark and Greenland.

• NATO allies warned that an American invasion would destroy the alliance.

• Several European governments emphasized that Greenland’s sovereignty is non-negotiable.

This crisis has shaken one of the fundamental assumptions of post-World War II geopolitics: that the United States and Europe share the same strategic interests.

Why Greenland Matters Geopolitically

Greenland is not merely a frozen island. It is one of the most strategically important territories on the planet.

Key Reasons for Its Importance

Arctic Military Control
Greenland sits between North America, Europe, and Russia, making it a critical location for missile defense and early warning systems.

Rare Earth Minerals
The island contains vast deposits of rare earth elements essential for high-tech industries.

New Arctic Shipping Routes
Melting ice is opening new shipping lanes that could transform global trade.

Strategic Competition With China and Russia
Control over the Arctic is becoming one of the main geopolitical battlegrounds of the 21st century.

For Washington, Greenland represents a strategic prize. For Europe, it represents a test of sovereignty and alliance trust.

The Strategic Contradiction: Asking Europe for Support While Threatening Its Territory

The central contradiction is obvious.

The United States expects Europe to:

• Support its war against Iran

• Share military and financial burdens

• Align politically with Washington

Yet the same administration is threatening to annex a territory belonging to a European NATO member.

This paradox has triggered serious debate within Europe.

Many policymakers now ask:

• If the U.S. can threaten Denmark today, could it pressure other allies tomorrow?

• Is NATO still based on mutual respect and sovereignty?

• Should Europe blindly support U.S. wars?

Europe’s Three Strategic Options

Full Support for the United States

Some European governments argue that supporting Washington remains essential.

Reasons include:

• NATO security guarantees

• Intelligence cooperation

• Dependence on U.S. military power

• Shared concerns about Iran’s nuclear program

Supporters of this approach warn that abandoning the U.S. would weaken Europe against threats from Russia and China.

However, this path risks reinforcing European dependence on American leadership.

Strategic Neutrality

Another option is limited involvement.

Europe could:

• Provide humanitarian support

• Avoid direct military participation

• Focus on diplomatic mediation

This strategy would allow Europe to maintain relations with Washington without fully endorsing the war.

However, neutrality could strain transatlantic relations and reduce Europe’s influence in the Middle East.

Strategic Autonomy

A third option gaining popularity in Europe is strategic autonomy.

Under this approach, the EU would:

• Develop independent defense capabilities

• Reduce reliance on the United States

• Pursue its own foreign policy priorities

Supporters argue that Europe must become a geopolitical power rather than a junior partner.

The Greenland crisis has accelerated this debate dramatically.

Energy, Security, and Economic Fallout for Europe

The Iran war is already producing serious economic consequences.

Energy markets are particularly vulnerable. Disruptions in Gulf energy flows have caused natural gas prices in Europe to surge, while the continent increasingly relies on U.S. liquefied natural gas (LNG) to replace Russian supplies.

At the same time, the conflict could trigger:

• refugee flows toward Europe

• terrorist threats

• cyber warfare

• economic instability

This means that even if Europe avoids direct military involvement, it cannot escape the consequences.

The End of the Post-War Transatlantic Order?

For decades, the transatlantic alliance was built on shared values, mutual defense, and respect for sovereignty.

The dual crises of Iran and Greenland suggest that this order may be entering a new phase.

Some analysts argue that Washington’s actions reflect a shift toward 19th-century great-power politics, where powerful states assert influence over strategic territories and weaker allies must adapt.

If this trend continues, Europe may face a historic choice:

• remain dependent on U.S. leadership

• or build an independent geopolitical role.

Europe’s Most Difficult Strategic Choice

The question of whether Europe should join the United States in its war against Iran cannot be separated from the broader crisis of trust within the transatlantic alliance.

Washington’s threats regarding Greenland have undermined European confidence in American leadership at precisely the moment when the United States is demanding solidarity in the Middle East.

Europe therefore faces a profound strategic dilemma:

• Supporting the U.S. could preserve NATO unity but reinforce dependence.

• Refusing support could weaken the alliance but strengthen European autonomy.

In reality, the answer may lie somewhere in between.

Europe is unlikely to abandon its alliance with the United States, but the Greenland crisis and the Iran war are accelerating a deeper transformation: the gradual emergence of Europe as an independent geopolitical actor in a multipolar world.

The real question is no longer simply whether Europe should join the war against Iran. The real question is whether the transatlantic alliance can survive an era in which even allies compete for power and territory.
