That seems pretty vague. Maybe give an example of Iranian behavior the would lead to Russia protecting Iran.
It's the zionist regime's behaviour that Iran must defend against. As it is US aggression that all the Brics countries must defend against. It's not as if Trump didn't concede that his own country is responsible for the war against Russia.
Russia has armed Iran with the capability to protect itself. That is, defensive capablity now that the Zionist regime has no ability to defend itself.And an example of Iranian behavior that would lead to Russia not protecting Iran. Is that fair to ask?
