Time has come to face the reality. Afghans are a cancer. First, this cancer needs to be removed from Pakistani society. Full repatriation of Afghans is the only solution. No fvcking ifs and buts. Just get on with the job and start removing Afghans in full force.
Second, this cancer needs to be cured along the border. Take full precautions against infiltration and misadventure in the border areas. Any hostile attempt to remove the fence needs to be responded with brute and indiscriminate force. If that means casualties on the Afghan side so be it. Use every tool and human resource at disposal to monitor and guard the border. Nothing is more sacred and important for a nation than guarding its soil.
No country allows its territorial integrity to be challenged by another hostile nation. Our response is weak and pathetic. We are under the illusion that talks can yield results. Talks won't yield any results. 17 years have gone waste and we should know that by now. Afghans have the backing of Indians, Americans and NATO forces. This isn't happening without their approval. This is happening under their noses.
Time has come to send a very clear message to US and NATO forces. Pakistan will target any Afghan miscreant attacking the fence. The US/NATO will be held responsible for the casualties since they are occupying that country.
