Why Iran’s power structure complicates a ceasefire
In the five months since the Iran war began on Feb. 28, each pause in fighting has underscored the complexities of ending it.
The June 17 memorandum of understanding opened a 60-day negotiating period over the Strait of Hormuz, sanctions and Iran’s nuclear and missile programs, but frayed within weeks as Iranian attacks on shipping prompted escalation.
The U.S. resumed strikes for 13 consecutive nights until it paused on July 24, only for the fighting to resume on Tuesday, with strikes overnight on Wednesday and Thursday. Iran’s army said on Friday it had launched attacks on strategic U.S. assets and military bases in Kuwait and Bahrain.
Whenever negotiations resume, Iran’s opaque power structure — spanning the Supreme Leader, the Revolutionary Guards, civilian government, commanders and other groups — will shape not only what is agreed, but whether any deal can be enforced.
Any ceasefire would have to pass through layers of command, and the Islamic Revolutionary Guard Corps (IRGC) commanders and Tehran-aligned groups may interpret the terms differently. Attacks attributed this week to Iran-aligned Iraqi militias on Saudi oil facilities and to Yemen’s Houthis on pipeline infrastructure show how groups sympathetic to Iran could widen the conflict.

Attacks on commercial shipping could become an early test of Iran’s wartime balance of power.
The U.S. has always emphasized it wants to see the Strait of Hormuz reopened without tolls. While Tehran’s civilian government is seeking economic relief and sanctions easing, elements within the security establishment may view continued pressure in the strait as an important source of leverage.
Iran’s civilian government hopes to unlock frozen funds to provide financial relief for the population of over 90 million Iranians crippled by decades of sanctions.

The government has long been undermined by the IRGC, who are “the dominant force on war and national security,” Sanam Vakil, director, Middle East North Africa Program at Chatham House, told CNBC.
They operate “missiles, drones, intelligence networks and regional armed partnerships, and during active conflict its commanders can exercise considerable autonomy,” she added.
“The civilian government still matters, and the president can shape diplomacy, economic policy and the work of the Supreme National Security Council, but he does not command the armed forces,” Vakil continued.
Who controls Iran’s military decisions?
President Masoud Pezeshkian leads Iran’s civilian government but ultimate authority over national security rests with Supreme Leader Ayatollah Ali Khamenei, while the IRGC exercises significant operational autonomy.
While the Supreme Leader has the final…
