We've been over this, fellas. We stole the resources from you and then bombed you with your own resources. The ones we used from our own coffers we were able to replenish because we weren't stuck at 400 infra cities - we had dozens of high-infra cities pumping out econ by the end of the war. That means that we had the luxury of being able to waste those resources without doing any harm to ourselves.
The "damage" of us using resources to bomb you into submission isn't damage at all: on paper it looks like we spent a finite amount, but the reality is that resources are not finite. They are infinite. We, due to being the victors on an obscene scale, were able to keep our economy going to fund this wasteful excursion. We didn't start running out of munitions or gas, we didn't lose our ability to fight, we weren't running a deficit: everything was completely fine on our end, because we could still produce those resources.
To put it another way, this is like getting into drink-off with a bartender. At the end of the day you may have made the bartender drink a lot of booze without paying, but you're going home to a lack of booze and they can just turn around and keep drinking.
