Background on this from Katehon:
Iran’s willingness to provide to Russia a military base Hamedan is a unique event in recent history of the state and evidence of a close strategic alliance between the two countries. This step links Russian geopolitics with Iran's interests in the region. There is no doubt that the Russian Aerospace Forces will protect the interests and security of both Russia and Iran. Iran strengthens its immunity against major opponents - the United States, Israel and Saudi Arabia, due to the Russian strategic presence. At the same time, Russia defends itself at a distance, moving the confrontation with the United States from Russia’s own border areas, closer to the marginal part of the Eurasian Rimland, and directly adjacent to the major US and British bases in the Persian Gulf (Bahrain, Oman, Saudi Arabia, United Arab Emirates).
