If there is anything to be learned from the disastrous counter-insurgency experiences in Iraq and Afghanistan, it is that the use of air power must be kept to a minimum, because the collateral damage crates more supporters for the insurgents.
Of course, this bit of knowledge appears not to have registered with the USAF, which is looking at an expansion of its role as US troops draw down.
This is why we need to be completely out. Every bomb we drop risks creating anothere Osama bin Laden.
