Is listing annexed territory listed in author details a valid reason to decline to review? I recently accepted a paper review based on an abstract.

On seeing the paper, at least one of the authors has listed their address as being within an unrecognized annexed territory, like this:


  Author, X university, /annexed territory/, /annexing state/


I am interested in the community views on whether this is reason to decline the  review. And, if so, should the reason be declared. 

At the moment, I intend to decline as I do not wish to legitimize the annexation in any way. On the other hand, I also do not wish to discriminate against individual researchers. 

How much should the decision depend on:


the perceived quality of work? 
personal links?
time since/extent of violence during annexation?


Can anyone offer a good framework for thinking about this? 



Points of clarification:


The authors do not use the term "annex", "annexed", or "annexing".
It is widely considered an illegitimate annexation (shared with a
majority of world states, UN)
The annexing state is not required for geographical location/postal
address (if anything makes it more confusing). 
I do not wish to act in a way that can be perceived as "activism", or to
"create a stink"...  
My argument is that adding to the record with the annexing state included
helps (albeit in a very minor way) its potential path to legitimacy.
Please do rebut...


"Annexing" might not be the correct term in this case, perhaps "occupying" is more accurate, I'm not sure - I think the general point of the question stands either way...

It might be helpful to reference what policies journals typically have on this?
Since you ask for a framework for thinking about it, I'll suggest that an action on your part that disadvantages the author, perhaps already a victim, won't bring justice. Probably better to ignore that detail and focus on what the author says, and honestly give the usual feedback. 

If you want to try to deal with the unfairness of the annexation, there are other places that would be more appropriate and effective. 

But your review is independent of any concept of "legitimization". You are giving a service to an author and a journal, not the occupying country.
