I took it out because the thread was veering into generic flamewar about Israel. Actually we often remove country names from titles because they trigger people into making more nationalistic comments, which are equal parts indignant and boring.
I wouldn't call that kind of title edit (taking out a country name) a policy. We have an ad hoc bag of tricks and sometimes we use one and sometimes another, depending on what feels needed. Do I know how unsatisfying that sounds? You bet. Do I get how it opens us to accusations of bias? I do, better than anyone else does. But the threads are too complicated to be managed with precise formalizations.
