The majority of the country has grown tired of the decade long war in Afghanistan and wants us out of there now. From Gallup:

Preference for US troop presence in Afghanistan

Our justification for continuing to fight in Afghanistan has shifted so many times I have lost count. At this point all we seem to be doing is trying to loosely prop up an incompetent central government which lacks any legitimacy with the populace.

Does anyone honestly believe that leaving in 3 months instead of 6 months, 16 months, or 600 months would make any real difference? Does anyone think that after over a decade in the country a few extra months will have any real impact?

There is no logical reason to continue this conflict and the American people want it to end now. We will leave the country eventually, it is just a matter of when.

The only important remaining question is how many more lives and billions of your tax dollars will President Obama insist on wasting there to prevent some Republicans and generals from saying mean things about him. This is the true test of real leadership and currently our noble peace prize winning president is failing.
