After the failure of the 1989 attempt to re-take the glacier, a new and much more daring plan was developed by the Pakistan Army to re-take the glacier by blocking the Indian supplies reaching the Indian base at the top of the glacier. The plan was ready in the late 1980s but was put on hold due to the fear that this operation could lead to an all-out war with India. Pakistan had recently been placed under US military sanctions for developing nuclear weapons and the Pakistani military hierarchy believed that they did not have the proper military deterrent if the situation escalated.
