A top US think tank “Centre for Strategic and International Studies (CSIS) ” says: Pakistan is still a sanctuary for the Taliban and the Haqqani network and more of a threat than an ally. It goes on to say that Trump administration should make it clear to Islambad that it will face sanctions if it continues to support the terror. Authored by Anthony H Cordesman, CSIS's Arleigh A Burke, the report said there has to be a better strategy and a better approach to both the military and civil dimensions of the war to provide a reason to stay in Afghanistan.

"The United States should make it clear to Pakistan that it faces a total end to aid, and the imposition of sanctions, if it continues to support the Taliban and tolerate the Haqqani network".

Russia should be told that any end to US sanctions will depend on it not supporting the Taliban, and the Unites States should reach out to China to make it clear that Chinese cooperation in dealing with Afghanistan and Pakistan can serve both Chinese and American interests, the report said.

CSIS said the US should make it totally clear that it will conduct a public annual review of its commitments to Afghanistan and the Afghan performance.

"It should make it clear that it can and will leave in the face of Afghan failure. If necessary, the United States should make good on such a threat," it said.
