There is a lot of information buried in the talk and history views of contentious pages like this - are there any sites or tools that help unpack some of that? What are the most frequently re-written bits of text? What parts of the article are most associated with certain editors (or groups of editors)? What about those editors - how many are anonymous or new? What other pages do those editors work on as well?

Even staying away from actual NLP analysis of the article or talk page, having a view of the dynamics of the construction of the article would be quite interesting.

Exactly. This seems a bit propagandist.

Something along the lines of "See, the pro-Russian Ukrainian separatist movement is only one building..."

"Occupation of government buildings then spread to other cities in the region."
