The 21-mile-wide Strait of Hormuz has become the world’s most dangerous stretch of water as tensions escalate between a US-led coalition and Iran. The vital shipping route, responsible for transporting nearly 20 percent of the world’s crude oil, is now facing severe disruption after Tehran imposed strict restrictions on vessels passing through the strait.

Although Iran’s foreign ministry insists the waterway is “not closed,” authorities have limited passage to only a few vessels considered non-hostile. Iranian officials say the restrictions are necessary due to “special conditions” and to prevent enemy ships from strengthening military positions in the region.

The situation has triggered fears of a global energy crisis, pushing oil markets into uncertainty and forcing Donald Trump, the current President of the United States, to seek international military assistance.

Trump Calls on Major Nations to Send Warships

Facing rising pressure over the supply disruption, Trump has reportedly asked several major economies — including China, France, Japan, South Korea, and the United Kingdom — to deploy naval forces to help secure the Strait of Hormuz.

The US administration argues that these countries are among the biggest beneficiaries of Middle Eastern oil shipments and therefore should share responsibility for protecting the route.

However, Trump’s appeal has not received the response Washington expected. Instead, several governments have reacted cautiously, while some have outright refused to join a military effort.

Allies Show Reluctance to Join Military Operation

Countries approached by Washington have largely avoided committing warships to the operation.

Australia made its position clear when Cabinet Minister Catherine King said Canberra currently has no plans to deploy a naval vessel to the region.

Meanwhile, Germany has also rejected participation. A government spokesperson said Berlin would not join the conflict or any mission to reopen the strait, emphasizing that the war “has nothing to do with the NATO defence alliance.”

In Asia, both Japan and South Korea have taken a cautious approach. Tokyo is reportedly studying the request within its strict constitutional and legal framework but is not considering maritime operations at this stage.

South Korea has also avoided a direct commitment, saying any decision would come only after careful review and consultations with Washington.

Even the UK government led by Prime Minister Keir Starmer has prioritised diplomatic engagement over military action.

Why Countries Are Hesitating

Experts say the hesitation is driven by political and legal concerns. Many US allies opposed the war with Iran from the beginning and are unwilling to become involved in a conflict they did not support.

Security analyst Rodger Shanahan, speaking to Al Jazeera, said participating in a mission to secure the strait could effectively draw countries into the broader war.

Another complication has been Trump’s public statements suggesting that countries relying on the oil route should “protect their own territory.” Critics say this framing has turned a global security issue into a transactional demand.

Legal restrictions also play a role. For example, Japan faces strict domestic laws regarding the deployment of military forces into active combat zones.

China Faces Strategic Pressure

The situation is particularly delicate for China. Trump has reportedly linked Beijing’s cooperation in protecting the strait to his planned summit with Chinese President Xi Jinping.

According to reports, Trump even suggested he might delay his visit to Beijing if China refuses to assist in the operation.

US Energy Secretary Chris Wright expressed hope that China would act as a “constructive partner.” However, the Chinese embassy in Washington has focused on de-escalation and diplomatic dialogue, avoiding any commitment to military involvement.

China maintains strong ties with Iran, making it unlikely that Beijing would risk deploying military assets in support of a US-led campaign against Tehran.

Naval Logistics Add Another Challenge

Even if countries decide to help, deploying naval forces is not an immediate process. Military experts say organizing coalition naval operations requires extensive coordination, planning, and deployment time.

Ships cannot simply be sent into a contested war zone overnight. Building a multinational naval presence in the Persian Gulf would require weeks of logistical preparation.

A Global Oil Lifeline in Dangerous Limbo

With no clear international consensus and naval support yet to materialize, the Strait of Hormuz remains in a dangerous stalemate.

While the United States insists countries benefiting from Middle Eastern oil should share the burden of protecting the route, many governments appear reluctant to enter a conflict they believe could spiral into a much larger war.

As tensions continue to rise in the region, the fate of the world’s most critical oil corridor now hangs in a fragile balance.
