Pakistan knows on whose behlaf afghanistan is doing all that stuff but still Pakistan is taking no action & being patient. Afghan delegates visits Pakistan and signs the memorendum but as soon as they land in afghanistan , they forgets what they have promised. Let's rewind when last month afghan president's advisor of national security Dr. Rangeen Dad Fars Panta visited islamabad and made promises to Pakistani government that they will help during the military operation in northen waziristan , in the boundaries of afghanistan and they also said that the terrorists who took refuge in afghanistan like Molvi Fazlu-ullah and Umer Khalid Kharasani will not help the terrorists with in the boundaries of afghanistan and they will stop him doing this but as Mr. Rangeen have reaced Kabul from Islamabad, they forgot what they have promised. This treacherous act by afgan government was condemned by Pakistani government. Before that the ambassador of Afghanistan in islamabad Mr. Jannan Musa Zai have met the Cheif of Army Staff General Raheel Sharif and promised that they will help Pakistan but alas they can not deliver what they promised. Some of the knows analysts have said as the tenure of Hamid Karzai in Afganistan is about to end and race for the presidency between Mr Ashraf Ghani and Abdullah Abdullah has been started, Pakistan's protest won't matter now much. May this argument by analysts is true but during these hard times Pakistan can not allow Afghanistan to help terrorists by aiding and proivding them refuge. They must remember the Afganistan's Intelligence Agencies who are plotting against Pakistan will follow the darkness and be gone forever.
