I think if we look at thi sissue from Pakistani perspective they are doing the right thing. They are seeing an oppurtunity wherein they can ehance their sphere of influence in the Indian subcontinent and encirlce India. They have good influence over Bangladesh and have many ISI operatives in Nepal. Myanmar is taken care off by China so if they and China can influence Sri Lanka it is good for them. Also they will be so close to monitor Indian Navy at the tip of India. And if anyone is to blame for this situation it is India and it's failed and confused policies. Sri Lanka did look upto India and was looking towards India for help and if India doesnot respond we cannot blame them. India and specially the UPA supported by DMK is all confused and the sufferer is India.
