I'm guessing no.
The whole problem with Afghanistan goes back to the Cold War. When it became warm in the 60's-70's, the USSR invaded Afghanistan, which was under NATO protection. Instead of sending men there, NATO sent guns, tanks and ammunition to Afghanistan. The Afghans beat back the Soviets, but were left well alone by NATO after the Cold War. The guns got into the wrong hands and militant groups such as the Taleban increased activity.
In more modern times, Afghanistan's chief exports are Heroin and Pirated DVDs (I have a friend from Afghanistan), most of which end up in 1st World countries. The money then goes to crime lords and eventually the militant groups. This means that, while the governments of the UK and US are funding the military, the criminals and drug addicts are funding the insurgents. This means that neither side will give up until completely destroyed, which will be almost impossible to do.
Territorial disputes and Islamic militants have been present in the Middle-East and Western Asia for many years without our intervention. I think we should leave them to it and focus on homeland security (ESPECIALLY due to the 2012 Olympics).
