Former US Secretary of State: Iran cannot be forced to surrender.
Blinken: Washington can pressure Tehran to negotiate, but it cannot force it to surrender.
Despite the damage to Iran's nuclear facilities, fissile materials and some of the country's nuclear capabilities still remain and there is a possibility of their recovery.
Iran has become stronger in certain areas. Tehran still has the ability to threaten the Strait of Hormuz and cause serious disruption to shipping.
The intensification of the war in the current situation would be "catastrophic." Any agreement requires that Iran also accept concessions.
