It should be noted that the entirety of the material leaked by Assange would be consistent with "Russian agent" theory (including variations along the lines of him not being directly in service, but getting backing because of being useful, even if he has his own reasons).

It might not be very obvious from inside US, but the whole mess with Iraq and Afghan wars, and especially everything that Wikileaks exposed about them, is one of the biggest providers of source material for Russian "whataboutism" (see also: https://en.wikipedia.org/wiki/And_you_are_lynching_negroes). In early 00s, it was mainly useful to justify the way Russia handled Chechnya. But from 2008 on, it became more and more important - South Ossetia, Crimea, Donbass, Syria.

With that in mind, leaks about any American administration serve those goals. Bush was certainly fair game. As do any leaks that concern any Western countries, their allies, and affiliated countries. Which happens to be exactly what Wikileaks has been focusing on.

Now, this doesn't mean that those leaks don't have any further value, in particular, to citizens of the affected countries. This part of it is where you generally see a lot of partisanship when judging said value.
