…you were using it for a reason as to why they wouldn’t put boots on the ground now. Even when funding was in place it was nothing other than a stalemate that neither side was going to win.
It obviously wasn't a stalemate until the Russians pulled back and then had time to dig in. If the West had been willing to provide F-16s and long range ordnance from the start, that might not have happened.
As for the situation now, Ukraine isn't asking for NATO troops, just for enough weapons and ammunition to continue the fight themselves.
Ukraine has already "won" to some degree, given the fact that there's not a puppet Government in Kyiv right now. What they're asking for now is sufficient support to defend what they hold and inflict as much damage as possible on their invaders.
You could reasonably argue that the quickest way to end this could be to give Ukraine as much material support as it asks for. Long range ordnance, aircraft, and ammunition, inevitably makes it considerably more painful for Russia to press on or even keep what they've got.
Putin might want to keep going, but sooner or later the poor bastards on the front line and their families won't. If Ukraine has to negotiate a peace, they need to be able to do so from a position of relative strength.
