If you click the link on that where it says "discuss" to the right of "Iranian victory" there's quite a lot of open discussion on whether to say won or inconclusive, with about 2/3 of people going for won.
I think quite a lot of people calling it biased don't really understand how it works - mostly by that sort of vote amongst the kind of people who went to university so I guess left of the Republican party but not too bad.
Not sure how you'd improve it except maybe a Ground News kind of approach of having two views - right wing sources say, left wing say. But then many controversies don't neatly split left-right.
Also it's not that locked. I could edit it for example - you need to have 500 edits. And I think anyone can chip in on the "discuss" bit.
Where, specifically, in that tediously long article does it say that Iran won the war? I found one citation of an external source whose title claimed that Iran won, and another claiming that there was "a significant shift in Iran's favor".
And I'm not surprised that the article is locked. If it were open to edit, there would be massive partisan re-writing of it, from all sides (Democratic, Republican, Iranian, Israeli, probably Chinese...)
