Ambassador John Herbst, director of the Atlantic Council’s Dinu Patriciu Eurasia Center, writes in a new issue brief entitled Partners or Competitors? The Future of the Iran-Russia Power Tandem in the Middle East that Russia and Iran are currently drawn into partnership over common regional interests and anti-American policies and sentiments despite centuries of historical rivalry. While their strategic partnership might not survive long-term shifts in either country’s politics, it remains inimical to US interests in the short-term.
