I think instead of threating Pakistan,Karzai should send his army to Kandahar to guard the rest of prisons because the prisoners keep escaping from Afghan jails !!! And I think Karzai has given this statement as a reaction to Lt Gen (R) Jamshed Gulzar's satatement which Karzai thinks has humiliated Afghan Army by saying " Pakistan Army is not Afghan Army". Hmmm Karzai is rightly offended !!
