[Rimbaud]

Any essay based on that comparison is going to be necessarily hampered by Tolkien's repeated refutation of any allegorical connection twixt the two. In fact, he would become quite heated when many insisted despite his denials that it was clearly an allegory - like any good work, however, it certainly holds applicability.

As Thinlómien says above, you're in the right place. This forum holds some of the better discussions on allegory / applicability in several fields from Catholicism to environmentalism to international politics as you suggest.
