Rov, are you related to Little Bobs?
AKA General Roberts, he tried a similar policy in The Second (sometimes called Great) Anglo Boer War, Kitchener implemented it and got the blame.
Afghanistan is a long game, change will come slowly to the region, we have to work within the confines of Afghan culture to achieve success, we will not (maybe never) recreate Kent in Kabul.
It's no good espousing western values and ideology to the people of Afghanistan, to bring about such a change means getting them to embark on the same torturous journey our own culture has taken to get here.
A simple example is pre revolutionary Iran (horrible place), the Shah enforced western ideas (most notably clothing) against the wishes of the people, it paved the way for his overthrow. Although many choose to overlook this, it is a fact.
History is littered with sponsored or enabled regimes without a popular movement behind it, and all the troubles that go with it, post war Greece (wanted Communism), post war Romania (didn't want Communism), Yalta ensured they got what they didn't want, Franco's Spain and the Irish Free State all bear witness to the sufferings of the people when their will is ignored.
