“Putin is already doing the maximum Russia can do.”
That’s just your ignorant opinion.
That’s just the reality. Putinist Russia is not omnipotent. They’ve already lost tank brigades to Ukrainian farmers and a flagship cruiser to Ukrainian fishermen. Just look at what 5 HIMARS have done to Russia. It’s not hard to project what 50 with the ability to hit Crimean ports can do. That’s what Ukraine will get if Russia makes a move toward Odesa or Kyiv.
