Freedom of Action is one I've seen on a few other national lists of Principles of War (if not that then something very like it). We tend to write them because we like checklists. there is nothing wrong with that as long as we don't see the list as the be all, end all. Rather, principles - seen in the less rigid way - can be useful in helping us consider whether we have taken account of the major areas of war that may present problems.

Unity of command is a principle that in most political-military conflicts the US honors in the breach. Ask yourself who is in charge of ALL USG activity (including military) in Iraq and Afghanistan. The answer is that there is no one person. In Iraq, neither Odierno nor Crocker is in charge of everything. thus the best that can be hoped for is unity of effort and that depends on the personal relationship.

Security is THE issue in both places. We've done pretty well in Iraq in the last couple of years, badly in Afghanistan.

My sense is that defining the objective was a problem in both places - again, better in Iraq recently than in Afghanistan. The objective in Iraq may well be an issue with the new Administration. It is certainly an issue in Afghanistan now and in the future. Hopefully, Petraeus is focused on that at his level but again, how will the Obama Administration see it?
