This Op-Ed in the New York Times was written by Eric Greitens, a former Navy SEAL, is the author of "The Heart and The Fist: The Education of a Humanitarian, the Making of a Navy SEAL."
The title provided him is an appeal to credibility. The SEALs are known as an elite, highly respected sector of the military, and as such, the article can be read with the perspective than an expert is speaking.
The argument made is that there are two separate wars going on- one against terrorism, and one to build the state government to a stable place. The writer argues that the terrorism war is going well, but that the latter is a hopeless cause which the United States has a moral obligation to build to a place of some stability, but cannot be "won."
He appeals to logos by writing clear "steps" that he proposes to achieve this. By making it seem manageable, it tempers the argument that "once the US has entered a military conflict, we must stay involved until it is resolved."
He also appeals to a visual, pathos side by making an analogy to a forest fire. He says, "Achieving that goal demands focus. Defeating a terrorist organization is like fighting a forest fire; there's never a clear moment of victory, and even after you've won, you have to watch carefully. The successes of the past decade have required discipline, focus and sacrifice from America's service members and their families. Now, to complete that mission, we must ask no less of our policy makers."
The respect with which he affords the relevant decision-makers makes the goal seem reasonable, easy to understand, and not a lofty goal to ask that both policy and in-the-field folks must work toward.
