It's a win.
The largest military the world has ever known was recklessly used towards a foe against decades of internal warning not to go there. People on both sides who didn't ask for this war paid with their lives.
High gas prices might have been a great cause for it ending, but the win for the world is that a escalation towards WWIII was averted, and that even idiotic leaders have learned that the world is a complex system and there's no such thing as a far away war anymore.
I actually think it is important to talk about winning and losing, more so when the overwhelmingly stronger party loses.
> even idiotic leaders have learned
Call me a cynic, but if you are dumb enough to start the war in the first place you are too dumb to learn any lesson.
