Iran closes Strait of Hormuz to Western shipping after US-Israeli strikes on Kharg Island, allowing only non-aligned nations to pass — global oil prices surge as 20% of world supply is disrupted, March 2026

The Strait of Hormuz, a waterway of unyielding strategic importance, has once again become a focal point of geopolitical tension. Iran’s decision to close this critical passage to Western shipping, in response to US-Israeli strikes on Kharg Island, underscores the intricacies of conflict and the delicate balance of power in the region. As I analyze this event, I am reminded of the fundamental principles that guide my understanding of war and politics: the inseparable relationship between the two, the inevitability of friction, and the crucial role of the centre of gravity in determining the outcome of any conflict.

First and foremost, it is essential to identify the political objective behind Iran’s actions. By closing the Strait of Hormuz, Iran aims to exert pressure on the West, particularly the United States, to reconsider its strategic stance in the region. This move is not merely a reaction to the strikes on Kharg Island but a calculated attempt to redefine the terms of engagement and challenge the existing balance of power. The political objective, in this case, is to demonstrate Iran’s capacity to disrupt global oil supplies and, by extension, influence the geopolitical landscape.

However, as with any strategic move, friction is inevitable. The closure of the Strait of Hormuz will undoubtedly face numerous challenges, from the logistical hurdles of enforcing such a blockade to the potential for international intervention aimed at reopening the waterway. the impact on global oil prices, while significant in the short term, may not be as pronounced in the long term, as markets adapt and alternative supply routes are established. The friction, in this scenario, includes not only the physical challenges of maintaining the blockade but also the diplomatic and economic repercussions that will inevitably arise.

The centre of gravity in this conflict is not the Strait of Hormuz itself but rather the international response to Iran’s actions. The key to understanding the dynamics of this situation lies in recognizing that the centre of gravity is the point at which the balance of power can be most effectively influenced. In this case, it is the collective stance of the international community, particularly the major powers, that will determine the outcome of this conflict. If the international community fails to present a unified front in response to Iran’s actions, the centre of gravity will shift in favor of Iran, allowing it to maintain its leverage over the global oil supply.

the role of passion, or the emotional dimension, cannot be overlooked in this analysis. The decision to close the Strait of Hormuz is as much a political statement as it is a strategic move. It reflects a deep-seated resentment towards Western interventionism in the region and a desire to assert Iran’s sovereignty. The emotional commitment of the Iranian people, as well as the broader Muslim world, to the cause of resisting Western dominance is a critical factor that will influence the trajectory of this conflict.

The fog of war, or the uncertainty that pervades any conflict, is also a significant factor in this scenario. The outcome of Iran’s decision to close the Strait of Hormuz is far from certain. The international community’s response, the effectiveness of the blockade, and the resilience of global oil markets are all variables that introduce a high degree of uncertainty into the equation. It is crucial, therefore, to approach this situation with a nuanced understanding of the complexities involved and a willingness to adapt to changing circumstances.

the closure of the Strait of Hormuz by Iran represents a complex geopolitical maneuver that must be analyzed through the lens of political objectives, friction, centre of gravity, and the interplay between rational strategy and emotional commitment. The outcome of this conflict will depend on the international community’s ability to navigate these complexities and respond in a manner that addresses the underlying political and strategic issues at play. As I often emphasized, war is the continuation of politics by other means, and the situation in the Strait of Hormuz is a poignant reminder of this maxim.
