She doesn't actually say it, but the one (or two) things it all comes down to, is money and the control of it. Wars like in Afghanistan are not meant to be won, they are designed to continue. All you need to do is lokk at the combat tactics the US (and its allies) forces use - Search&Destroy - then you can already tell that this is going nowhere. Just as it did in Vietnam. But thats the whole point of it all: its supposed to continue, not to end. Because that way the money keeps flowing towards the military industrial complex.
