India’s Vice President Hamid Ansari joined Pakistan Prime Minister Nawaz Sharif and Presidents Ashraf Ghani of Afghanistan and Gurbanguly Berdimuhamedow of Turkmenistan in the ground-breaking ceremony of the Turkmenistan-Afghanistan-Pakistan-India (Tapi) gas pipeline in Mary, Turkmenistan. Ansari hailed the pipeline as a major step towards regional integration. It is to be completed by 2018. Will the Afghan political and security situation allow that to happen?
