Russia is allied only with themselves.
That doesn’t make them bad, nor good.
They will do what is best for Russia.
If that means dealing with Iran, they will
If that means fucking with us, they will.
That is the way any strong nation should operate.
Situations should be evaluated based on our, national, best interest.
Not what’s best for muh queen, frogs, muh refugees, or even our “greatest” allies.
That may or may not mean dealing with Russia.
