Ambassador Olga Stefanishyna says Russia is “absolutely a factor” in the war with Iran

Olga Stefanishyna, the Ukrainian ambassador to the U.S., told “Face the Nation with Margaret Brennan” that Russia is “absolutely a factor” in the war with Iran as Russia was “investing in regimes like Iran, Venezuela, and Syria, just because they thought it’s not possible to have the resolute action as it is now taking place with Iran and as it was before in Venezuela.”
