^^ I know you are sarcastic.
seriously, to govern Afghanistan they need to establish and train the local governance.
US brought complete stability in Iraq, first by eliminating Al Qaeda, Mahdi army militias by brutally launching military operations and then by steadily wiorking to train governance and administration.
Afghanistan has weak governance in remote area, that leads to opium and other illegal arms trade to flourish. Then there are regular raids, attacks from Talibanis from across the border in Pakistan.
The real problem is eliminating competely, Taliban first, opium ban and measures to improve economy, governance can be worked out after that.
