Iran's military planning ahead of the war helped blunt the impact of US-Israeli strikes on its arsenal and leadership, according to Western military intelligence assessments.
The assessments say Tehran still retains the ability to respond if the ceasefire breaks down, despite sustaining massive damage to its infrastructure and killing its most senior leaders.
Operational planning undertaken in anticipation of the conflict was effective in preventing the destruction of its missile and drone capabilities as well as maximizing the impact of its military response, people familiar with the matter said.
Iran retains solid reserves of long-range missiles and thousands of drones in its armory, according to assessments provided by European and Gulf officials.
Some Western officials claim the US would need to conduct around two to three more weeks of strikes to completely degrade Iranian capabilities, but others say it could take longer and Iran's industrial and nuclear capabilities may still not be wiped out.
