Worth thinking about.
Russian support for anti-American Iran and support for their atomic bomb and missile should tell us all we need to know about Putin’s “friendship” to the West.
They, in turn, would point to America's support of (and promotion of) the Saudi regime and its repulsive ideology of Sunni Wahabbism.
Russia to a large degree really only has two exports: OIL and WEAPONS.
They need the cash. Oil prices aren't where Russia (or OPEC) "needs" them to be to support their populations.
In Russia's case, they have a secondary market called WEAPONS to sell and make money. OPEC has oil and that's it.
Not surprising that Russia is selling weapons like crazy in the middle east right now. More accurately, has been for decades.
