Yes at this moment this really looks like a pyrrhic victory, i am not sure about the last part of that sentence as he could sell himself as a victorious leader, but time will tell.
Regarding comparing with Desert Storm, yes Russia will suffer much bigger casualties, but they had to rush in a ground offensive as unlike Iraq they knew that Ukr will receive huge help. Nobody was helping Iraq.
But i believe that Russia will lose less people, hw and money (as cost of war, the effect of sanction excluded) in Ukraina than US lead coalition lost in Iraq until today, even if Russia doesn't not advantage over Ukraina even near as US coalition had over Iraq
No Russian economy actually is not in ruins.
