Hezbollah leader says in event of war, Iran won't be alone

Hezbollah's leader says Iran won't be fighting alone in the event that United States launches launch a war against it

Nasrallah was speaking to supporters at a rally marking the 40th anniversary of Iran's Islamic Revolution and the overthrow of the shah.

"If America launches war on Iran, it will not be alone in the confrontation, because the fate of our region is tied to the Islamic Republic," he said.

Speaking via a large screen, Nasrallah said America is set to retreat from the region and has no real option to squeeze Iran except with sanctions.

"We see the struggle in the region may escalate and may take different forms but in all cases, today the Islamic Republic is the strongest state in the region ... and America is headed for more withdrawals and retreats from the region," he said.

Nasrallah spent over an hour extolling Iran and the Islamic revolution's political and economic accomplishments.

The group dominates the political and military landscape of Lebanon and possesses tens of thousands of trained fighters as well as an array of sophisticated armaments. Its intervention in Syria on the side of President Bashar Assad also expanded its influence and reach in the region.
