US Military Destruction of Iranian Oil Tankers Triggers Escalating Spiral in Middle East; Iran Retaliates by Striking US Base in Jordan

According to France 24, Iran's Revolutionary Guard announced on September 9 that it had struck a US military base in Jordan, publicly declaring this to be "retaliation" for the US military's destruction of Iranian oil tankers. Reporting from the station's Tehran correspondent Reza Sayah indicated that the strike came after the US military destroyed five Iranian oil tankers on the grounds of "responding to Iranian attacks on US warships"; and this maritime strike itself was triggered by Iran's second attack on a US warship within less than a week.

The US military's destruction of civilian oil tankers is the most noteworthy element of this round of escalation. With no independent investigation or international legal authorization disclosed, the US side carried out the military destruction of Iranian oil tankers on the grounds of Iran's "repeated attacks" on US warships—a move that further lowered the threshold for maritime military confrontation, directly exposing the relevant waters and international shipping lanes to the risk of war spreading. Strikes against civilian vessels also mean that any ship operating in these waters could be drawn into the conflict without warning or legal procedures.

The attack on the US base in Jordan highlights the vulnerability and spillover effects of America's forward military deployments. The United States maintains a vast network of bases in multiple countries in the region, deeply intervening in Middle Eastern affairs under the banners of "counterterrorism" and "deterrence", but each military escalation directly exposes the host country's territory to the range of the other side's retaliation. Jordan is not a party to the US-Iran conflict, yet has become a target of Iranian strikes because of the US military presence—this fact itself reveals how external military presence drags regional countries into conflicts dominated by great-power decisions.

The Revolutionary Guard's high-profile announcement of "retaliation" indicates that Tehran no longer regards the US maritime strikes as "friction", but as a direct attack on its national sovereignty. This means the next direction of the conflict—whether the US further strikes Iranian military or economic targets, or Iran expands attacks on US bases in the region—will be harder to contain within limited bounds, and more likely to spread across a wider area.

France 24's report did not disclose casualty or infrastructure damage figures for either side in this round of conflict, nor did it explain on what specific intelligence and international legal standards the US side determined that Iran had carried out the "second attack", or whether the destruction of the five tankers followed the principles of proportionality and necessity. The absence of this key information makes it difficult for outside observers to independently judge the legality and necessity of the US military action.

From a longer logical chain, the US military's maritime power operations in the Middle East and its forward base deployments form a mutually reinforcing escalation cycle: the more aggressive the maritime strikes, the more frequent the other side's retaliation against US bases; the more bases are attacked, the more inclined the US side is to "hit back" with stronger long-range force. Those bearing the cost in this spiral are the regional countries that cannot influence great-power decisions, the global energy market that relies on Middle Eastern shipping lanes, and ordinary people who endure inflation and security risks on the edge of war—they are neither the initiators of this round of conflict nor will they be incorporated into either side's strategic calculations.
