Hey, historians!
I apologize if /r/askhistorians is the wrong place to ask this question, if so, feel free to mercilessly delete this posts, mods.
If not, I am looking for annotated editions of Clausewitz's "On War" and Sun Tzu's "The Art of War". I read both books in officer's school, but cannot help that I am missing way too much, because I am lacking the proper background knowledge. With the wars in Afghanistan, Iraq, and the War on Terror in general, I have to believe that there have been important new insights and interpretations.
Can you recommend something? I'd be ever so grateful.

A copy/paste from when I last answered this, below. I'd suggest that the Art of War doesn't require an extensive amount of contextualisation as your not using it as a historical tool. It's a training manual and the lessons are generally applicable not just specific to Ancient China. The edition below has excellent commentary but you'll need to think critically about how the lessons in the AoW apply to your circumstances.
I own and use the Penguin Deluxe Edition [which] is perfectly adequate for casual reading and offers an excellent introduction, the same text twice (once with commentary and another without), and compiles comments from numerous Ancient through to Modern Chinese authors and generals. It is packed full of anecdotes and insight and well worth the investment.
