The above photo is from Rear Admiral Fox's office, and describes the desired "End State" situation in Iraq. I think the use of the word "state" in the title makes for a nice double entendre, and as such, helps convey the magnitude and the situation and the size of the project. Also on the card, at the bottom and out of the picture, is this final line: "An ally in the war on terror."
So this is what "victory" in Iraq looks like.
So, how realistic is it? That's a good question - the only consensus appears to be the fact that what is needed most, beyond what is being done, is more time. Unfortunately, thanks to the political cycle, this is precisely what we do not have.
