It's been difficult to find the operational objectives[1] of the war laid out plainly, which ACOUP once again does expertly (as best as any expert can do at this stage, anyway).

The Siege of Gondor writeup[1] is worth reading by itself, but I think rereading it with Putin juxtaposed to Sauron would retroactively give LotR that much more relevance and gravitas.
