The agreement between Pakistan and US that has happened.

WASHINGTON, Nov. 18 — A new and classified American military proposal outlines an intensified effort to enlist tribal leaders in the frontier areas of Pakistan in the fight against Al Qaeda and the Taliban, as part of a broader effort to bolster Pakistani forces against an expanding militancy, American military officials said.

Militants have extended their reach beyond the tribal areas.

If adopted, the proposal would join elements of a shift in strategy that would also be likely to expand the presence of American military trainers in Pakistan, directly finance a separate tribal paramilitary force that until now has proved largely ineffective and pay militias that agreed to fight Al Qaeda and foreign extremists, officials said. The United States now has only about 50 troops in Pakistan, a Pentagon spokesman said, a force that could grow by dozens under the new approach.
