Iran's Northern Frontier
Iran's geography offers few viable land approaches. The Iranian Plateau is enclosed by mountains and deserts that impose severe constraints on mechanised movement and sustained logistics. Air power can strike Iran. It cannot hold it.
The Northern Approach
From a purely physical perspective, the least restrictive terrain lies in Iran's northwest, where the Armenian Highlands and South Caucasus meet the Iranian Plateau. Here, elevated but broken terrain, river basins, and valleys connect Anatolia and the Caucasus to Iran without crossing the deepest Zagros barriers.
The Aras River Basin
The Aras River basin marks this interface, forming a zone where movement into Iran's periphery is historically and geographically more feasible than elsewhere. This does not constitute a defined invasion corridor. It represents a relative weakness in an otherwise formidable geography.
Strategic Assessment
Crucially, this physical possibility is constrained by politics. Any force seeking to exploit it would require secure staging areas, bases, and logistics north of Iran, within the South Caucasus — one of the most geopolitically complex regions in Eurasia.
