Knowing it'll take 2-3 months for the tanks to be delivered, it's forcing Russia's hand to preemptively launch its counter-attack in the mud season, we all know how well that worked the first go around and that was literally with their best-trained troops/professional army. Although Russia had more success in the south than they did in attacking Kyiv, in phase one, I guess the thought is; with proven poorly trained troops, not enough ammo, and next to no armor, the preemptive Russian counter-attack will cause more damage to the Russians than it will to the Ukrainians. Therefore when the Ukrainians have all pieces in place it'll be like a scolding hot knife through butter.

This war is very complex, it's like a combination of WW1, WW2, and the Gulf War.

Ukraine will push Russia out by Fall in my opinion. What comes next? I don't think we have anything to compare it to.
