"Well, there may be some complaint implied in the fact that at least 25 percent of the Afghan army are Taliban infiltrators. The 25 percent is the official US estimate."

Oh dear, just because something is an estimate does not make it fact. But let's take a look at this "fact" of yours or rather of the US (Who in the US by the way?).

Current ISAF troop levels in Afghanistan at the moment are ~101,000.

Current strength of the ANSF is ~350,000.

So if your "fact" is indeed a "fact" then Taliban infiltrators account for ~87,500 men.

So what on earth are they waiting for? Each man could rise up tomorrow and kill one "foreign infidel invader" a piece, the really quick could kill two or three and it would be "game over".

One thing goes against this "fact" of yours - the ANSF are predominantly Uzbek, Tajik and Hazarra - very few are Pashtuns.

Your "fact" or more accurately this "estimate" is a complete and utter crock.
