How far would Russia go to help Iran and vice versa?

Should Iran face more sanctions if it continues helping Russia to wage a brutal war against Ukraine? I talked to Barbara Slavin, a distinguished fellow at the Stimson Center in Washington and a lecturer in international affairs at George Washington University. We also discussed how far would Russia go to help Iran and vice versa, how the Russian war affects the Middle East, China in the region, and how weak or strong is the regime in Tehran. Listen to our conversation. And if you enjoy what I do, please support me on Ko-fi! Thank you. ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://ko-fi.com/amatisak⁠
