Iran War Escalation: Risks of Costly, Complex Conflict

Published: 14 March 2026. The English Chronicle Desk. The English Chronicle Online

The Israeli-US war against Iran and its proxies has entered a perilous stage, becoming a proving ground for competing concepts of military escalation, each with the potential to trap the attackers in a more complex and costly conflict.

Despite killing Iran’s supreme leader, Ali Khamenei, and other key figures in the opening stages, the clerical regime remains intact, and its stockpile of highly enriched uranium is unsecured. Airstrikes are intensifying, but the strategic objectives of the campaign remain unclear.

Tehran has responded with a “horizontal escalation” strategy, widening the conflict geographically and increasing costs for Washington and the global economy, particularly energy markets. Iran’s strikes on Gulf states and shipping through the Strait of Hormuz aim to create political and public pressure on US allies, exposing cracks in the US-Gulf alliance.

Experts warn of an escalation trap, in which tactical military successes do not translate into strategic gains. Robert Pape, a US historian, explains that after initial tactical success, the attacker may double down, moving up the escalation ladder without achieving political objectives. “We are likely at stage two, on the cusp of stage three,” Pape said, cautioning that the conflict could become protracted and far riskier.

Trump’s approach has been criticized for relying on the accuracy of weapons and an “illusion of control,” pushing Tehran toward a model of escalation with broader global implications. Meanwhile, Israel has signaled further escalation, preparing operations in Lebanon against Hezbollah if rocket fire continues.

Former US envoy Robert Malley notes that US escalation decisions may be shaped more by Trump’s psychology than strategic calculation. He warns that escalating military involvement—including special forces deployment or occupation of parts of Iran—could trigger unpredictable Iranian retaliation, including terrorist attacks against US targets.

Jack Watling of the Royal United Services Institute highlights the internal US debate between professional defense planners aiming for limited objectives and Trump’s desire for coercive control over Iran. For Iran, retaliation in the Gulf is designed to restore regional deterrence. Even if current strikes slow, Tehran could continue its horizontal escalation strategy, maintaining long-term pressure on shipping and regional stability.

Robert D Kaplan points to the “slippery slope of incrementalism,” cautioning that incremental actions could eventually lead to deeper US involvement, mirroring historical conflicts such as Vietnam.

As the situation evolves, the conflict’s trajectory remains uncertain, with risks of prolonged escalation, economic disruption, and wider regional instability. The coming weeks are likely to test both US military power and strategic judgment in an increasingly multipolar world.
