Petraeus should concentrate on killing Taliban and not offending them. If they want to burn Korans in Florida, let them be and Petraeus should live with it.
Can’t you just see Gen Patton excoriating his tank commanders for anti-Nazi rhetoric written on shells and tanks? Or Eisenhower telling a church in Florida that burning Mein Kampf would infuriate Germans, and not to do it?
Burning the koran would seem to stifle his effort as it gives the locals mores reasons to take the wrong side.
But, hey, help your self. Freedom of speech and right to taunt and all that. If my son was in Afghan I'd be kicking some butt on the first match I see lit.
