The wording of the most recent edit is needs tweaking. Reading the source provided, Hunter wrote in opposition of a complete withdrawal of U.S. forces, an unreliable Afghan Leadership, concerns regarding roadside bombs, and what he saw as "Obama administration's other shortcomings" which he termed "mixed messages" to American service members and the world. And as stated by the Administration in 2012, there are were no plans for a complete withdraw; which had changed as recently as recently as this month to possible withdrawal after 2014. Therefore, upon closer review the summarization of the source is wrong.
As for the second part, I would say the best way to word it would be something like:

So in the end I am proposing the following wording:
In 2011, Hunter wrote in ''[[Politico]]'' that he is opposed to a complete withdrawal of American forces from Afghanistan, and was concerned of the challange of an "unreliable Afghan leadership".{{cite news |title=How to handle Afghanistan |author=Duncan D.

The alteration of the quote is keeping with MOS:QUOTE.
