Vladimir Putin and Masoud Pezeshkian have signed a Comprehensive Strategic Partnership Agreement, signaling a deepening alliance between Russia and Iran. This agreement focuses on military, nuclear, and economic cooperation, and is part of Russia's broader strategy to secure its interests in the East, particularly with the US. Iran's strategic pivot towards the East is a response to Western sanctions and reflects its desire for a significant role in shaping a new global order. The partnership treaty, however, raises concerns about the hidden costs of such secretive alliances and Tehran's role in Moscow's broader foreign policy strategy.
