"Ever since he took office two years ago, Obama has made the deadly drones a key instrument in his fight against the militants in Afghanistan and Pakistan. The drones are also being used liberally to target militants in Yemen and Somalia." 
The Afghan war in its tenth year has expanded into a far broader conflict, one which grows in both scope and lethality with each passing week and will escalate yet further before it begins to wind down, if it ever does.
President Obama's pledge last year to "draw down" U.S. and NATO combat forces from South and Central Asia - they are also stationed in Kyrgyzstan, Tajikistan and Uzbekistan - next year is now revealed to be the transparent political manipulation it was from the start.
Is there a scenario in which the US and NATO could actually "turn the tide" against these insurgents, given the absolute level of corruption of the governments of both Pakistan and Afghanistan?
Not probably without reinstituting the draft in the US, and putting 500,000 pairs of US boots on the ground in Afghanistan, and there are questions as to whether even such a show of force could make a difference, as the old Soviet Union found during their "military misadventure" in Afghanistan.
We will continue to stay in Afghanistan, and lose miserably, because this administration actually doesn't know what else to do, and doesn't want there to be a "Saigon moment" in Kabul.
The moral and ethical problem with this war, publicly funded and fought, is that it has been fought essentially for potential private profits. These were supposed to come from the installation of pipelines with which to control Eurasian oil (hasn't happened to date), and from the drug trade (which, after the invasion and occupation, has grown exponentially).
We have never had, and continue to not have, the moral high ground on our side. And because of this, ultimately, the US is destined to lose this war, after all the blood and money spent.
