Interesting article, but ultimately feels meaningless. Am I going to go out of my way to support politicians who agree with these two author's views on urban warfare, when the world faces so many real actual problems?

That response suggests you have no children, spouse, or loved ones serving in the US military or planning to serve in a combat function. Others may, and thus come to a different conclusion as to its meaninglessness (good Scrabble word). Doesn’t place the expansiveness of your worldview is a positive light...

And as a grammar Nazi aside, are there unreal actual problems, or real virtual problems (aside from virtual machines and the like)?

You're right about "real actual", of course, but sometimes it's fun to misuse language for flavor.
