For years, the prospect of a US–Iran war has returned to the forefront whenever tensions rise in the Middle East. Fiery rhetoric, military build-ups, tightened sanctions, and exchanged messages all suggest that confrontation is imminent. Yet, despite limited and direct military clashes at various points, events have repeatedly stopped short of sliding into a full-scale, open war. This recurring pattern raises a legitimate question: if war always seems close, why does it never fully erupt?
The answer does not lie in a lack of hostility or a shortage of capabilities. Rather, it is rooted in the complex web of political and military calculations that make a comprehensive war an extremely costly option for all parties, despite continued escalation.
From the United States’ perspective, war with Iran is not a preferred choice. Washington, already engaged in major international confrontations, from the war in Ukraine to intensifying competition with China, understands that opening a wide front in the Middle East would drag it back into a long war of attrition it has sought to escape for more than a decade. A war with Iran would not be quick or clean. It would mean confronting a large state with unconventional deterrence capabilities and a regional network of influence capable of expanding the battlefield far beyond Iran’s borders.
On the other side, Iran also shows little interest in a direct war with the United States. Despite its escalatory rhetoric, Tehran recognises that an open confrontation could threaten the very structure of the regime and impose economic and social costs that would be difficult to contain internally. As a result, Iran has adopted a strategy based on indirect deterrence, managing confrontation through regional tools and carefully calibrated signals, while avoiding crossing lines that would trigger a comprehensive American response.
This fragile balance has turned the conflict into a form of managed confrontation. The landscape is not free of limited clashes, indirect operations, or exchanged military messages, but all are tightly controlled and treated as pressure instruments rather than steps toward total war. Washington brandishes force to constrain Iranian behaviour, while Tehran demonstrates its ability to respond without moving toward the point of no return.
In this context, Israel plays an important role in pushing the conflict toward escalation, while not holding the final decision. Israel views Iran as a long-term strategic threat and seeks to weaken it by all possible means. However, a full-scale US–Iran war could open scenarios that are impossible to control and whose repercussions would reach deep into Israel itself. For this reason, Tel Aviv prefers a logic of limited strikes, prolonged attrition, and intelligence operations over an open confrontation whose course it cannot fully direct.
Arab regimes, meanwhile, adopt an extremely cautious stance. Even where political differences with Iran exist, these states understand that any wide war would be fought on the region’s soil, infrastructure, and societies before it ever touched distant capitals. Accordingly, they favour keeping the conflict within containable limits, regardless of how intense it becomes, rather than risking an uncontrollable explosion.
The most significant factor explaining the absence of a comprehensive war is that the US–Iran confrontation has evolved into a political instrument. It is used to apply pressure, manage balances, and send messages, without becoming an end in itself. In this case, war is not a means to secure clear gains, but a gamble that could overturn the entire regional order.
Moreover, the absence of a clear vision for the aftermath of war further complicates the decision. What follows a full confrontation with Iran? Does it mean toppling the regime? Who fills the vacuum? How would a state the size of Iran be governed in an already unstable regional environment? Washington has no convincing answers to these questions, nor any guarantees that the outcome would be better than the existing reality.
For this reason, confrontation continues in a grey zone form: escalation without resolution, pressure without a declaration of war, and messages that are read with extreme caution. It is a conflict that advances rhetorically but retreats at the decision stage, because its costs exceed its potential gains.
In conclusion, the state of no war reflects not weakness, but a harsh rationality shaping the behaviour of the opposing parties. Everyone understands that igniting a war may be easy, but extinguishing it is nearly impossible. Between threats and retreats, the Middle East remains suspended in a grey space where crises are managed rather than resolved, and explosions are postponed rather than prevented.
Thus, the US–Iran war persists as a permanent possibility, invoked when needed and contained when danger looms, encapsulating the region’s condition: suspended conflicts, delayed decisions, and a price paid by others.
