The problem the west has is that you can't print physical things like artillery shells or create soldiers out of thin air. Ukraine's capacity to fight has been degraded to a point where the front is now collapsing, and no amount of money is going to change that.
Hope you're right but the bombs don't have to come out of thin air if that $8B just goes straight to Lockheed and Haliburton ukraine is going to keep getting enough arms to justify continuing to fight for a little longer.
I'm also gonna put on my tinfoil hat and say ukraine also doesn't wanna end the war because I'm pretty sure the reason zelensky keeps complaining all the money we send isn't enough is because 50% is getting lost in the couch cushions of Ukranian officials overseeing the war. The checks keep cashing and there's zero percent chance them or their families sees combat so why stop now.
Libs seem very unconditional-surrender-brained about this conflict. Even concept of considering Russian desires in a potential peace settlement makes them so fucking angry.
Eventually, once there are no more avenues left to help Ukraine without triggering nuclear war or losing thousands of NATO soldiers, they will simply pretend to have won the war, and pull all remaining support.
