The United States Looks Set To Launch Military Strikes Against Iran

The United States looks set to launch military strikes against Iran within the coming days if diplomacy fails to avert escalation, BBC security correspondent Frank Gardner writes but while potential targets are largely predictable, the consequences could be wildly different depending on what happens next.
U.S. President Donald Trump is reportedly weighing targeted military action against Iran, including missile systems, commanders and possibly nuclear facilities, to pressure Tehran amid political unrest and nuclear disputes Iran has warned it would treat any attack limited or otherwise as an “all‑out war,” and is on high alert to respond.
State media in Tehran has also showcased a provocative mural depicting retaliation against U.S. forces signalling deep defiance and readiness to push back if attacked. Based on analysis of what could unfold, from the least harmful to the most damaging:

1. Surgical strikes, minimal civilian harm quick political shift
   The U.S. could carry out precise air and naval strikes targeting Iran’s Islamic Revolutionary Guard Corps (IRGC), Basij militias, missile sites and nuclear programme, aiming to degrade Iran’s capabilities while limiting civilian casualties. In the best‑case scenario, a weakened regime could eventually transition to a more open political system.
2. Regime survives but moderates policies
   Iran’s government might endure the strikes but choose to moderate its regional behavior for example, scaling back support for proxy militias, cutting back nuclear ambitions, and reducing harsh internal repression. This would resemble outcomes seen elsewhere where military action changed tactics but not leadership.
3. Regime collapses and military rule emerges
   Rather than leading to democratic renewal, Iran’s political system may fracture, and the IRGC or other military leaders could seize control, maintaining authoritarian rule. This is widely seen as a plausible post‑strike scenario by analysts.
4. Iranian retaliation beyond its borders
   Iran could strike back against U.S. forces and allies in the region using missiles, drones or asymmetric attacks even though it cannot match U.S. military power directly. Tehran’s ballistic missile and drone capabilities pose real risks to bases in countries like Bahrain and Qatar, and allied territory.
5. Mining the Strait of Hormuz
   A key economic threat Iran could employ is laying mines in the Strait of Hormuz a strategic chokepoint through which about 20‑25 % of the world’s oil and LNG flows. Disruption here would send energy prices soaring and complicate global trade.
6. Swarm attacks and asymmetric naval retaliation
   Iran’s Revolutionary Guards Navy could use “swarm” tactics deploying many fast boats and explosive drones simultaneously to overwhelm U.S. naval defenses. While unlikely to sink a U.S. warship, such attacks could damage vessels and be a significant blow to U.S. prestige.
7. Collapse followed by chaos
   In the worst scenario, the Iranian regime could collapse without a clear successor, igniting civil war, ethnic conflicts (e.g., Kurds, Baluchis), refugee crises and regional instability. This could destabilize the Middle East far beyond the immediate conflict zone. Gulf states and U.S. allies have expressed deep concern that any attack could rebound on them via missile or missile‑proxy responses. Iran’s forceful warning that any attack equals “all‑out war” underscores the risk of rapid escalation into wider conflict.
   Disruption of shipping lanes like the Strait of Hormuz would not only affect oil and gas prices but could ripple across global markets, affecting inflation and energy security worldwide.
   Previous U.S. and allied strikes on Iran’s nuclear facilities in 2025 showed how complex and unpredictable military action in the region can be, including potential for proxy wars and long‑term diplomatic fallout.
