Consider the sentence (1):
The Allies reprinted Axis propaganda during WWII, and the Axis reprinted Allied propaganda. There were some exceptions, but clearly they saw [adjective] value in the documents.
or similarly (2):
The Allies reprinted Axis propaganda during WWII, and the Axis reprinted Allied propaganda. There were some exceptions, but clearly they found the documents [adjective].
The [adjective] I'm looking for has the approximate meaning of "that which provides insights [into enemy motivations]". The best options I've been able to come up with thus far are:
- probative or expository in (1), which aren't great matches
- forensic in (1), which seems far too formal
- enlightening or insightful in (2), which carry the strong connotation of agreeing with or being swayed by the propaganda and therefore aren't suitable here
I have a niggling suspicion that there is a single adjective closer to the intended meaning but my mental thesaurus fails me.
Any suggestions would be appreciated.
