The militant group’s leader admits that the toppling of Syria’s president, Bashar al-Assad, cut off an important land route from Iran.

For Iran’s theocratic government, it keeps getting worse. Its decadeslong strategy of building an “Axis of Resistance” supporting militant groups and proxies around the region is falling apart.

The Bashar al-Assad regime’s rapid collapse deals a heavy blow to Iran’s “axis of resistance” and its ability to project power in the region, and it raises fears Iran will focus more on developing its nuclear program.

Assad, after rebel forces swept into Damascus this weekend, shattered Iran's network of influence in the Middle East but Israel, the United States and Arab powers must now deal with the risk of instability and extremism from the mosaic of forces that replaces him.

And now Iran’s longtime stalwart ally and client in Syria, President Bashar Assad, is gone. As dawn broke Sunday, rebel forces completed a lightning offensive by seizing the ancient capital of Damascus and tearing down symbols of more than 50 years of Assad's rule over the Mideast crossroads.

Iranian Foreign Minister Abbas Araghchi addressed the “complex challenges” facing Syria and the broader region in a recent discussion, a recent report said. The report reflects the importance that Iran places on trying to find a way back to Damascus after the fall of the Assad regime.
