Tl;dr: Not many Ukrainians want to push into a longer war in Russia, they just want to get the fuck back to "normal" and rebuild and foritfy their nation.

I mean I understand western powers giving billions, expecting a massive push, but just hear me out...these people are fighting for their home. They don't want to push into Russia and kill Russians or kill innocent people, their lives have been ruined already. War crimes have been committed against Ukraine, massive amounts of explosives detonated over entire cities. Land mines cover hundreds of miles by now, and Russia made sure to do as much damage as possible, long lasting damage. People will work hard and push hard, when they are in survival mode, and defending their lands is def something they are very righteously doing. Expecting them to counter attack and become the very thing they have rallied against, come on....the Western powers that "give" Aid, are going to want to make money, and a prolonged war with billions in sales of weapons, is of course what they want.

Ukraine just wants to rebuild, fortify and make sure this shit never happens again, what they don't want, is to go into Russia and land grab for power. It is no mystery why the counter offensive just doesn't have the same ferocity.
