The Geopolitics of Iran: Holding the Center of a Mountain FortressTo understand Iran, you must begin by understanding how large it is. Iran is the 17th largest country in world. It measures 1,684,000 square kilometers. That means that its territory is larger than the combined territories of France, Germany, the Netherlands, Belgium, Spain and Portugal — Western Europe. Iran is the 16th most populous country in the world, with about 70 million people. Its population is larger than the populations of either France or the United Kingdom.
Under the current circumstances, it might be useful to benchmark Iran against Iraq or Afghanistan. Iraq is 433,000 square kilometers, with about 25 million people, so Iran is roughly four times as large and three times as populous. Afghanistan is about 652,000 square kilometers, with a population of about 30 million. One way to look at it is that Iran is 68 percent larger than Iraq and Afghanistan combined, with 40 percent more population.
More important are its topographical barriers. Iran is defined, above all, by its mountains, which form its frontiers, enfold its cities and describe its historical heartland. To understand Iran, you must understand not only how large it is but also how mountainous it is.
Iran’s most important mountains are the Zagros. They are a southern extension of the Caucasus, running about 900 miles from the northwestern border of Iran, which adjoins Turkey and Armenia, southeast toward Bandar Abbas on the Strait of Hormuz. The first 150 miles of Iran’s western border is shared with Turkey. It is intensely mountainous on both sides. South of Turkey, the mountains on the western side of the border begin to diminish until they disappear altogether on the Iraqi side. From this point onward, south of the Kurdish regions, the land on the Iraqi side is increasingly flat, part of the Tigris-Euphrates basin. The Iranian side of the border is mountainous, beginning just a few miles east of the border. Iran has a mountainous border with Turkey, but mountains face a flat plain along the Iraq border. This is the historical frontier between Persia — the name of Iran until the early 20th century — and Mesopotamia (“land between two rivers”), as southern Iraq is called.
NOTE, the facts are useful although a reader might disagree with some of the subjective conclusions.
