War on North-West Pakistan

The War in North-West Pakistan is an armed conflict between the Pakistani Army and Islamic militants made up of local tribesmen, the Taliban, and foreign extremists.It began in 2004 when tensions rooted in the Pakistani Army's search for al-Qaeda members in Pakistan's mountainous Waziristan area (in the Federally Administered Tribal Areas) escalated into armed resistance by local tribesmen.
Clashes erupted between the Pakistani troops and al-Qaeda's and other militants joined by local rebels and pro-Taliban forces. The Pakistani actions were presented as a part of the War on Terrorism, and had connections to the war and Taliban insurgency in Afghanistan By the military’s own reckoning, the past two operations against the tribal militants in South Waziristan ended in failure. The Jan 2004 operation led to the infamous Shakai peace agreement in April 2004, followed by another agreement with the now-dead Tehrik-i-Taliban chief Baitullah Mehsud on Feb 5, 2005.
In late January last year, the military launched Operation Zalzala with the stated goal of dislodging Baitullah Mehsud from his stronghold. The operation did not cause even a tremor and only 12 days later, were authorities struggling to revive the dead Sararogha agreement.
Pakistan has also lost more than three times the number of its troops compared to the number of US troops killed in Afghanistan. As of 2009, the Pakistan Army and the Frontier Corps are currently being trained in counter-insurgency warfare by the US and British Governments. The conflict, as well as terrorism in Pakistan has cost Pakistan $35 billion.
