Russia's main goal with us, and maybe the EU too, to create descent in the populous. That is why there are so many bots on social media. One bot talks up the right and another bot talks up the left.
Me, if I was in charge - I would resupply the newer NATO countries in eastern Europe with no fanfare. Resupply with a few tank brigands, air support, and men to support both.
Again, I would just do it and wait to see what Russia does. I suspect nothing. Then I would go about taking a way some of Russia's natural gas sales to the west by supplying them with gas.
Once accomplished I would say nada till Valdimir started to whine. At that point I would say, "stop acting like a little man trying to be big, or I will cut off all of your gas sales to the EU."
Natural gas and crude oil exports is the entire Russian economy. What else do they export? WWII Mosin Nagets?
