I both agree and disagree. This fence is a requirement now because of decades of failure in foreign policy. We haven't built any links with the Afghan people, only with groups and power players, much like the colonialists of the past. We had a massive opportunity during Taliban regime, we wasted it. We had another one when re-patriating people. we should have offered people the chance to leave alone and take their family in a years time if they felt it was safe. We could have helped setup schools, or other minor facilities in the areas our refugees were moving too. We could have liased with Taliban to ask for security for returning refugees, we could have provided seed for farming, all sorts of little support. Instead we push them out the door with a kick up the backside for good measure!
