Karzai: Sign US-Afghan Security Pact Next Year President Hamid Karzai urged tribal elders Thursday to approve a security pact with Washington that could keep thousands of U.S. troops in Afghanistan until 2024, but he added a wrinkle that he prefers his successor sign the document after elections next April. Karzai's move could be an attempt to avoid taking personal responsibility for an agreement that many Afghans see as selling out to foreign interests. His remarks to the 2,500 members of the consultative council known as the Loya Jirga came as President Barack Obama made a personal plea for quick passage of the agreement in a letter promising to respect Afghanistan's sovereignty and only raid homes when U.S. lives are at risk. The Loya Jirga is widely expected to approve the agreement, and Karzai's remarks could be seen as last-minute move to force the gathering to ask him to sign the long-delayed accord - thus shifting the responsibility for the deal away from him to the elders. The White House urged that the security pact be signed by the end of the year, with spokesman Josh Earnest saying a failure to finalize an agreement in the coming weeks "would prevent the United States and our allies from being able to plan for a post-2014 presence" in Afghanistan. Military leaders in the U.S. and NATO widely acknowledge that the nearly 350,000-member Afghan National Security Forces are not yet ready to take on the Taliban alone after a war that has lasted more than 12 years. The Afghan forces, however, have held their ground this summer after taking control of security around the country from foreign forces. Senior U.S. military officials have repeatedly stressed that Afghan forces still need at least three to four years of training and mentoring take on a resilient Taliban insurgency that shows no sign of abating or compromising. U.S.-backed attempts to start peace talks with the Taliban have failed so far. If there is no security deal, the U.S. has said it will pull all its forces out of Afghanistan, as it did when Iraq failed to sign a similar agreement. Washington's allies have also said they will not remain without a U.S. presence, and the exit of all foreign forces would jeopardize the more than $8 billion that has been pledged annually to fund Afghan security forces and help with the country's development after 2014. A signed accord means that about 8,000 U.S. troops could stay for another 10 years, which is the duration of the Bilateral Security Agreement. Although their main role will be to train and assist the Afghan military and police, a small number of U.S. forces will continue to hunt al-Qaida members. The Obama administration has yet to specify how long U.S. troops might actually remain to complete the training and support mission, and the agreement extends far past Obama's tenure as president. U.S. officials have not yet disclosed how many troops they want to keep in Afghanistan after 2014. U.S. officials have said the U.S. and NATO could keep between 8,000 and 12,000 troops. Asked whether the bilateral security agreement sets up the prospect of U.S. troops staying in Afghanistan for years and years, Secretary of State John Kerry told MSNBC on Thursday that nothing like that was being contemplated.
