Why the US-Israel war on Iran failed

The war waged by the United States and Israel against Iran deserves a place in contemporary international relations textbooks. Not because it overturns everything we know about power, but because it shows how the use of power is changing.
Classical approaches to relations between states still matter and the balance of power hasn’t disappeared. Military superiority still counts, but the consequences of using force have become less predictable than before because coercion no longer produces linear outcomes. This applies not only to direct military intervention, as in the case of Iran, but also to sanctions and other forms of pressure.
If one strips away the rhetoric, which all sides require for domestic reasons, the picture is straightforward. A coalition that was clearly stronger, consisting of the US, Israel, and the Arab Gulf states, failed to achieve the objectives it set for itself when it launched a military campaign against a clearly weaker adversary: Iran and its allied groups in the region, with likely limited support from Russia and China.
The aim was to deliver a swift, crushing blow to a regime considered weakened by external pressure and internal divisions. Donald Trump’s demand for “unconditional surrender” captured the mood perfectly as the assumption was that Tehran would buckle under the pressure.

The opposite happened and the attacking side’s superior forces were met with unexpectedly high resilience. Iran didn’t collapse after the initial decapitation strike and instead it reorganized, mobilized and, most importantly, cast aside many of the constraints that had previously limited its response.
This is where one of the defining features of the new era came into view as asymmetrical counter-action. Iran couldn’t match the US and Israel in conventional strength, but it didn’t need to because it used the tools available to it in ways that offset many of the enemy’s advantages.
First, it moved to close the strategically vital Strait of Hormuz, something it had long threatened but never before dared to do. Second, it struck not only American targets in the region, but also the assets of key US partners. Third, it relied on large weapons stockpiles which, although inferior to those of the US and Israel, were sufficient to inflict serious damage on countries unused to absorbing such blows. Fourth, Iran demonstrated a tolerance for damage substantially higher than that of its enemies.
The current outcome speaks for itself as none of the issues over which the US and Israel went to war has been resolved. Everything has once again been deferred to future negotiations and everyone understands that negotiations in the tradition of Persian diplomacy mean tenacity and patience.
In essence, after an intense armed conflict that threw the whole world into turmoil, the status quo that had been destroyed at the beginning of the war has simply been restored. The Strait of Hormuz is to be reopened to shipping, although even the conditions for that remain unclear as both sides interpret them differently.

The experience of recent years shows that the scope for achieving political objectives through military force is narrowing. The weaker side’s capacity to resist is growing, while the stronger side’s willingness to accept serious risks, especially risks to its own domestic stability, is diminishing. This applies to many conflicts, but it is particularly visible in the Middle East.
The broader political consequence is the relative weakening of the dominant power in the shape of the US. Trump has shown that he is deeply reluctant to become embroiled in another full-scale military confrontation, having failed to achieve his objectives in a war he himself began....
