I just read a thread on twitter by a German I am following. It appears that Russia and Iran are developing and very tight trade relationship in weapons.
Specifically, Iran is delivering drone and ballistic misiles in return for Russian weapons and captured western weapons. (Iran had a western based military until 1980.) Iran seems to be pretty good at reverse engineering western weapons.
My thoughts turn to this though. How hard would it be to ship 250 pounds of plutonium down the Volga river across the Caspian sea to Tehran?
The following is my uneducated speculation.
Or simply put 10 pounds of well shielded plutonium in each fighter delivered in place of explosives in the missiles attached to the hard points. In a matter of months Iran would be a nuclear power with advanced fighter and long range ballistic missiles tipped with fission weapons.
Back stopped with nuclear weapons, Iran could open a second front against Saudi Arabia.
End personal speculation.
Finally, there are rumors Moscow is going to run an offensive against Kiev. I suspect that sooner is better than later. The ground is not frozen yet, but once it is, an early move would help avoid the mess the Russians faced last spring when the early thaw caught their columns and forced them the paved roads. (Not that hubris was the biggest problem there)
My speculation
I am not convinced that Russia wants to take Kiev, are even a large part of Ukraine. Handing the west a broken country and millions of refugees and a massive energy crisis may be a better outcome than an out right victory. “To the victor goes the spoils” In this case it is more like “To the victor goes the expense”.
