Russia Today is a horrible source for information. Russia Today is a state owned news agency with an obvious anti-US bias.
Fair News is not conducted this way:
http://www.youtube.com/watch?v=-ugCIjzHptAThe front page of RT includes a USA link.
http://rt.com/usa/All of the headlines serve to give the United States a bad image. RT's rhetoric and literature reek of bias and can't be trusted. RT is essentially Russian Propaganda Today.
That being said, if you actually read the document it doesn't say anything about any amount of troops staying in Afghanistan. US Military strategy in Afghanistan has changed. We'll probably see troop reduction in 2014 because the war is different now. US Foreign policy is to kick down doors in the night, train people, and kill people through camera lenses.
The government is going to shift money with this shift in strategy and alot of soldiers will get sent home. Afghanistan is a failed country. The ANSF is horrible and firefights/Self Delete bombings/etc are ingrained into contemporary Afghan culture. The persistence of extremist also means that there probably won't be an end to this but life goes on.
