Ukraine is being liquidated for the corruption value. There is no intention to win or even compromise, just to prolong as much as possible. As long as the war goes on, money can flow. The weapons are only a tool because the people sending the weapons see them as their own property which they can use as they see fit. Do they care about readiness for a future conflict? I doubt it. That is what the nukes are for. If we run out of conventional weapons and it looks like a loss will cost them their gains, they will use the nukes.
“Do they care about readiness for a future conflict?”
All of Europe is increasing military budgets and arms production. They received a salutary shock in Feb 2022, and a lot of minds were suddenly changed. I suggest you do some research before you commit to an opinion.
That about sums it up.
