From the article --
"Deploying additional forces could backfire, however, if the United States and its allies don't devise a coherent strategy to defeat the Taliban insurgency, strengthen the Afghan government, bolster the country's economy and deprive Islamic militants of their safe haven in neighboring Pakistan."

Spent a tour as an advisor at the ministerial level.

Deploying forces without a strategy "could" backfire -- how 'bout WILL backfire. Killing Taliban cannot solve the problems of Afghanistan. Think I ought to get paid for that deep insight.

Sorry for the rant. Yes, the solution has to be holistic. We need to do better. A better wrap up of the challenges is at CSIS by Tony Cordesman.
