The Second Blockade: Why Has the U.S. Returned to a Failed Strategy?
WANA (Jul 15) – The United States has once again resumed its maritime blockade against Iran, a move that comes after the collapse of previous understandings between Tehran and Washington and the return of military tensions in the region. The decision has once again turned the Strait of Hormuz into the center of one of the world’s most sensitive geopolitical confrontations.
The U.S. Central Command (CENTCOM) has announced that American forces are prepared to reimpose a maritime blockade targeting vessels linked to Iranian ports and coastal areas. The move follows Washington’s declaration that previous understandings with Tehran are no longer valid and that the path toward confrontation has been reopened.
However, the U.S. return to the option of a maritime blockade is not merely a military response to recent developments; it also reflects Washington’s renewed attempt to reshape an equation that failed to produce the results it expected during the first phase of this policy.

Over recent months, the United States has sought to pressure Iran through a combination of economic restrictions, military actions, and maritime limitations, aiming to force Tehran to accept Washington’s demands.
Yet Iran has continued to maintain control over the Strait of Hormuz, kept alternative trade routes active, and refused to make the concessions sought by Washington on issues such as its nuclear program, regional relations, and defense capabilities.
Now, with the blockade being revived, the central question is whether the United States will achieve a different outcome this time, or whether the Strait of Hormuz will once again become the scene of a prolonged confrontation between the two sides.
Who Controls the Rules? The Strategic Contest Over Hormuz
WANA (Jul 15) – If Washington’s objective were simply to reopen the Strait of Hormuz, this chapter would likely have ended long ago. What continues to draw the United States back to the Strait after months of confrontation is not merely the movement of oil tankers, but what it sees as a challenge to a […]
Why Did Washington Return to the Maritime Blockade Option?
The U.S. decision to revive this strategy can be viewed within the framework of the Trump administration’s efforts to rebuild pressure on Tehran. From Washington’s perspective, controlling energy flows and limiting Iran’s economic capacity are among the tools that could increase the costs of continued confrontation for Tehran.
However, the experience of the first round of the blockade showed that while maritime pressure can affect trade and the economy, it does not necessarily lead to a change in the political calculations of the opposing side.
During the period between the two rounds of blockade, Iran managed to reduce some of the pressure by using various trade channels, strengthening economic partnerships, and developing alternative mechanisms. This has transformed the Strait of Hormuz from merely an economic or military issue into a symbol of the broader power struggle between Tehran and Washington.
For the United States, the waterway represents a test of the credibility of its maximum-pressure strategy and its ability to influence the behavior of a regional rival. For Iran, the Strait of Hormuz remains a key element of its security calculations and one of its most important strategic levers in confronting external pressure.

Hormuz: A Small Waterway With Global Importance
The Strait of Hormuz is one of the world’s most important energy transit routes. Any disruption in this passage could have consequences far beyond the region, affecting global energy markets, shipping costs, and the economic security of countries around the world.
For this reason, any confrontation in the area is closely monitored by global actors. A full maritime blockade is also not an easy operation in practice, as it requires a significant military presence, advanced intelligence capabilities, and continuous control over a complex maritime environment.
U.S. officials have previously acknowledged the challenges of such an operation. Naval forces would need to simultaneously monitor shipping movements, protect their own assets, and remain prepared to respond to potential actions by the opposing side.
Meanwhile, Iran has also demonstrated that it will seek to use regional and international capacities to reduce the impact of maritime and economic pressure.
The Hormuz Crisis: A New Opportunity for Israel
WANA (Jul 13) – Against the backdrop of recent developments, Israel is likely the most satisfied actor on the scene. Following the clashes of recent days — and especially the failure of the latest mediation efforts over the Strait of Hormuz — the prospects for a final resolution of the disputes between Iran and the […]
Public Sentiment in Iran: Economic Concerns and Emphasis on Adaptation
The return of the maritime blockade has been met in Iran primarily with economic concerns, as maritime restrictions could affect trade, oil exports, and the import of goods. However, part of Iranian society also believes that the country has faced external pressure for years and will continue to seek ways to reduce its impact.
Mohaddeseh Foroutani, a graduate student, told WANA News that Iranians seek peace but believe Washington is using various tools to increase pressure on Tehran.
“We Iranians are looking for peace and goodwill, but the United States is willing to use any measure to achieve its goals. A maritime blockade is one of the tools that can be used to increase pressure during negotiations or for other objectives,” she said.
Foroutani added that dealing with such circumstances requires new approaches, saying: “Our actions must be creative and innovative so that we can achieve a more effective position, whether in political, economic, military, or other fields.”

Milad, a Tehran resident, also told WANA News that the maritime blockade could create economic difficulties, but Iranian society has experienced similar conditions in the past.
“This economic blockade will certainly create disruptions, but with the resilience of the people, this historic stage can be overcome,” he said.
He added that Iran has previously sought to reduce the impact of restrictions through measures such as expanding economic relations with other countries, creating alternative routes, and engaging with non-Western partners.

The Future of Hormuz: More Pressure or a Return to Negotiations?
The return of the maritime blockade indicates that the dispute between Tehran and Washington remains at a stage where military and economic tools have overshadowed diplomacy.
For the Trump administration, the issue is not only about restricting exports or controlling maritime routes; it is also about demonstrating that U.S. pressure can still influence Iran’s behavior.
In contrast, Iran is seeking to show that it can withstand external pressure and increase the costs of continuing such policies for the other side.
However, past experience has shown that confrontations in the Persian Gulf rarely lead to quick solutions. Both sides possess significant capabilities, but the cost of a prolonged conflict would be substantial for regional actors and the global economy.
The key question now is whether the renewed maritime blockade can lead to a new political agreement, or whether it will mark another stage in a prolonged strategic rivalry.
