Russian President Vladimir Putin and his Iranian counterpart Masoud Pezeshkian have signed a 20-year strategic partnership, deepening military ties between their countries. The agreement includes increased cooperation in security services, military drills, warship port visits, and joint officer training. While the treaty does not include a mutual defense clause or specific mention of arms transfers, it does state that neither country will allow their territory to be used for actions that threaten the other. The partnership is likely to worry the West, as both Russia and Iran have suffered setbacks in the Middle East and there have been reports of Iranian drones being used in the Ukraine war.
