If you get an infection, you get a fever; the fever is your body dealing with the infection. If you get traumatized, your mind and your brain have a reaction to that trauma. If you're not dreaming about it, something's probably wrong.

Traditional Albanian society was based on a clan system and was further divided into brotherhoods and bajraks. The bajrak system identified a local leader, called a bajrakar, who could be counted on to provide a certain number of men for military duty.

Combat isn't where you might die -- though that does happen -- it's where you find out whether you get to keep on living. Don't underestimate the power of that revelation. Don't underestimate the things young men will wager in order to play that game one more time.

No one will remember that President Obama supported the Arab Spring if it eventually fails and the region collapses back into the political Dark Ages. If we actively engage these movements with advice, with money, and, when necessary, with military force, then we get a vote in how it all turns out.

Here's an easy way to see if a war movie is being truthful: If you see an explosion on a faraway hillside and the sound of the explosion and the detonation of the bomb happen at the same time - if they're putting the sound and the vision together in the same moment - they're going toward our cultural understanding of war, not the reality of war.

One interesting thing I found was that if you take an affluent modern society and collapse it during a crisis, like a war or a natural disaster, people begin relating in a more ancient, organic way.
