The NATO alliance is facing a major test as tensions grow between the United States and its European allies. The latest crisis, linked to conflict involving Iran, has exposed deep divisions. At the center is Donald Trump, whose sharp criticism has raised fresh doubts about NATO’s unity and strength.
A Longstanding Alliance Under New Strain
The NATO alliance has faced many serious challenges throughout its long history. Created after World War II, its main goal was to protect member nations and maintain peace, especially across Europe. For decades, it acted as a powerful shield, discouraging potential enemies and helping prevent large-scale conflicts between major powers.
In recent years, NATO has been tested by the ongoing Russia-Ukraine War. This war sharply increased tensions with Russia and pushed member countries to rethink their military readiness and cooperation. While there were disagreements on strategy and spending, the alliance managed to stay united and continued supporting Ukraine in different ways.

Now, a fresh crisis linked to tensions with Iran has created new pressure. Unlike previous challenges, this situation is unfolding far from Europe, raising difficult questions about NATO’s role and response.
Trump’s Anger and Rising Tensions With Europe
The current strain within NATO began after tensions in the Middle East sharply escalated on February 28. Following the outbreak of conflict linked to Iran, the United States looked to its allies for immediate support. One of the key expectations was for European nations to help secure the Strait of Hormuz, a narrow but crucial route through which a large portion of the world’s oil supply passes. Any disruption there can impact global energy prices and trade.
However, European countries chose not to deploy their naval forces to the region. This decision was seen in Washington as a lack of support during a critical moment. As a result, Donald Trump reacted strongly. He has long argued that NATO members should contribute more equally, and this situation appeared to reinforce his belief that the alliance is unfair to the United States. His public remarks questioning NATO and hinting at a possible U.S. pullback have added to the tension.

On the other side, European leaders have defended their position. They say the United States did not provide clear or detailed requests about what kind of military help was needed. There was also uncertainty about whether any operation in the Strait of Hormuz would take place during the active conflict or afterward, leading to hesitation.
At the same time, existing disagreements have made matters worse. U.S. policies toward Russia and earlier controversial comments about Greenland have already strained trust. Together, these issues have deepened divisions within the alliance.
Fears Over NATO’s Core Promise
The biggest concern now is about the core promise of NATO, known as collective defense. This principle means that if any one member nation is attacked, all other members are expected to come to its defense. For decades, this idea has acted like a safety shield for Europe, discouraging enemies from taking aggressive steps.
However, this long-standing trust is now facing serious doubts. Experts warn that even without a formal withdrawal, the United States could simply choose not to act in a crisis. As commander-in-chief, Donald Trump has the authority to decide how U.S. military forces are used, which creates deep uncertainty among NATO allies.

This is especially troubling for European countries because they rely heavily on American military strength. The United States provides advanced capabilities such as satellite intelligence, air defense systems, and logistical support. These are critical during emergencies and cannot be easily replaced in a short time.
Because of this growing uncertainty, some European leaders are beginning to rethink their defense strategies. There is increasing discussion about strengthening their own military systems and reducing dependence on the U.S. This shift reflects a deeper concern that NATO may no longer function in the same unified way as it has for many years.
