The main problems of South Asia are balochistan, Sindhi,MQM ect.These moments are comming from the hearts of ppl due to thier oppression by rules.These all are sins of pak. Another issue is support to talibans this also sin of pak.The kashmir issue is created and fuelled by pak since 1989 and it will come down as none of the ppl have complained that they had any issue atleast till 1989. The real solution to south asian problem (or to most of the terrorism faced by world today) is divide pak into pieces and handover some pieces to India and some to Afghan and may be even some pieces like taliban regions to china so that chinese will teach how simple it would be to deal with so called global terrorism.
