After aligning strongly with Israel and Saudi Arabia, a lot of ways have been given to regions such as Russia that crave for land. As of yet, Russia has not considered pursuing its partnership with both Saudi Arabia and Israel, at Iran’s expense.
Not only Russia, but a number of other major powers such as India have shown opposition to the Trump administration’s approach to stymie the trade with Iran. Moreover, by the end of 2018, Russia also aims to make use of national currency in settlement with Iran. Hence, Russia’s stance is rather clear since it had not aligned itself.
