And why would the UK do that Meherdad -- Germany has paid Israel for the dehumanization and murder of 6,000,000 people in the 20th century less than $20 billion dollars (the original amount was less than 2 billion, this is inflation adjusted) -- And Israel has a voice on the global stage. Afghan are going to get $100 billion from the UK ?!?!? -- that hash is good stuff I guess. Afghanistan today is referred (in the DC community) as "That Dust Bowl" - People care for Afghanistan and Afghans about as much as they do for "The Republic of Congo" (Can you point it out on a map).
Further Afghanistan has already gotten $100 in assistance and spending from the West -- not not much has it?
There is a video of Gen. Sher Mohammad Karimi (on youtube, bin trying to find it) the current Chief of Staff of the Afghan Army telling a group of cadets that Afghan land runs to the Indus -- what Durand line?!
Pakistan can afford the insurgency - if it fixes if economy, normalizes relations with India - Afghanistan cannot - if the Afghans wish to burn their house further - so be it.
Further on the matter of peace, Afghanistan needs to come to terms with its structural faults -- there is a reason Ghani is crying uncle -- do yourslef a favor watch Ghan's videos on Pakistan from a few years ago -- he's more menacing than the rest of em. This new lovey dovy affection he has for Pakistan is really a large object he finds in one of Afghanistan's fundamental orfice.
