ISLAMABAD Kabul and Islamabad are actively considering a proposal to sign a comprehensive bilateral security treaty ahead of the exit of US-led NATO forces from the insurgency-ridden Afghanistan. Well-placed diplomatic and official sources told The Nation on Sunday that if it gets positive nod of the governments of Afghanistan and Pakistan both the sides would be able to tackle security related challenges in the wake of foreign troops exit from Afghanistan. The proposed deal, if materialises, would lead to lasting peace and stability in the region, the sources said. The sources said that the proposal originally dished out by Pakistan envisages sharing of intelligence, training of Afghan police and National Afghan Army troops and their requirements of defence weapons. The sources were of the view that Pakistan has been emphasising the need for evolving a bilateral mechanism ahead of the exit of NATO/ISAF troops from Afghanistan to continue joint efforts to combat terrorism. Pakistan, the sources said, would open up its defence facilities for training of the Afghan troops and national police, besides meeting the other defence and security related needs. The sources said that Pakistan has discussed the proposal with the Afghan government during Prime Minister Yousuf Raza Gilanis recent visit to Kabul. Afghan President Hamid Karzai has accepted the proposal and assured the Prime Minister Gilani that his government would positively consider it, the sources in the Foreign Office confirmed to this scribe. They were upbeat that once the plan was approved, both the neighbouring countries which have suffered a lot over the years due to terrorism and militancy, would be able to tackle the security related challenges effectively.
