For weeks, Iranian officials have downplayed the fall of their ally in Syria. But an important general has offered a remarkably candid view of the blow to Iran, and its military’s prospects.

We were defeated and defeated very badly, we took a very big blow, and it’s been very difficult,” Esbati noted.

For the first time, Iran publicly admitted its defeat in Syria following the collapse of Bashar Assad's regime. Brig. Gen. Behrouz Esbati called the loss a "big blow" and said the defeat had been difficult for the Islamic Republic.
