Will the 'Iron Gate' close Iran's land borders?

The US Central Command announced the launch of Operation Iron Gate aimed at obstructing land shipping routes and routes across the Caspian Sea and tightening the blockade on Iran. The new force consists of 20 civilians and military personnel coordinating with the CIA to prevent the transfer of advanced weapons, dual-use technologies and sanctioned materials. Analysts believe the land blockade may have limited impact due to the large number of crossings and maritime borders, while Washington says the naval blockade has prevented $25 billion in exports.
