seeming obsession with problems in Iraq and Afghanistan, much to the expense of other national security priorities.
Additionally, they are expressing concerns of whether or not the President and his administration are going to be able to stick with their goal of withdrawing U.S. troops from Afghanistan by the middle of 2011.

Obama's new deployment, estimated to cost $30 billion a year, will bring the total number of U.S. service members in Afghanistan to roughly 100,000. NATO allies are expected to add at least another 5,000 troops to the more than 40,000 they have already contributed to the U.S.-led mission.

The new strategy is designed to eliminate al Qaeda in Afghanistan and help the Afghan government defeat the Taliban insurgency, while also bolstering Pakistan's anti-terrorism efforts.

The latest strategy will be a "fiasco" that will lead only to more dead Americans, the Taliban insurgency said Thursday.

Nancy Pelosi, Speaker of the House, indicated doubts over the new strategy of the White House in Afghanistan, and has requested the White House to brief all members of Congress about the plan in detail.

"I think we have to handle it with care - listen to what they present", she said.

Secretary of State Hillary Clinton, Defense Secretary Robert Gates and Joint Chiefs of Staff Chairman Adm. Mike Mullen answered a range of often hostile questions during their second day defending the president's war plan on Capitol Hill.

"Over the last days I've heard a number of people saying that we are in Afghanistan today because that is the place from which we were attacked" on September 11, 2001, said Senate Foreign Relations Committee Chairman John Kerry, D-Massachusetts.

"Frankly, eight years later, that's simply not good enough. We have largely expelled al Qaeda from Afghanistan."

Kerry stressed the need to build on U.S. assistance to neighboring nuclear-armed Pakistan, which has been increasingly targeted by Islamic extremists.

"Much more discussion is warranted on whether the Afghanistan mission is so central to our core national security that it necessitates huge spending increases and the deployment of a large portion of our finite combat capability," said Indiana Sen. Richard Lugar, the ranking Republican on the committee.

"In essence, we have to ask whether the costs of this deployment are justified in our overall national security context and whether we are mistakenly concentrating our forces to fight a terrorist enemy in a specific location even as the global terrorist threat is becoming increasingly diffuse."

Lugar cited, among other things, the proliferation of terrorist cells across Africa, Europe and the Middle East.

He also agreed with Kerry that greater attention needs to be paid to Pakistan.

"The potential global impact of instability and a nuclear-armed Pakistan dwarfs anything that is likely to happen in Afghanistan," he said.

"Throughout the history of Afghanistan, the Afghans have not been subjugated through deceit, ploys, material power, troop reinforcement and military might of the foreigners," Taliban leaders said in a statement released Thursday. "Therefore, the reinforcement of the American troops and other tactics will not have impact on the status quo. But the reinforcement will provide better opportunity for the mujahedeen to launch offensives."

Clinton, Gates and Mullen all asserted that Afghanistan remains the central front in a global war on terror and is key to U.S. national security interests.

Afghanistan "is the place from which we were attacked," Mullen said. "Should we be hit again, it's the place from which I am convinced the planning, financing and leadership will emanate."

Sen. Russ Feingold, D-Wisconsin, voiced the attitude of many liberal Democrats by saying he is pleased Obama set a date to start a withdrawal, but is disappointed the president is escalating the U.S. presence without providing a firm end date for all American military involvement.

"I do not support the decision to prolong and expand a risky and unsustainable strategy in the region," Feingold said.

Mullen rebuffed one of the most common critiques of the date by asserting it is "not arbitrary at all." July of 2011, he pointed out, will be the third summer for U.S. Marines in Helmand province -- a base for extremists in southern Afghanistan -- "and we will have a clear indication (by that point) which way this is going."

Sen. Robert Menendez, D-New Jersey, argued in turn that the date is "clearly inspirational."

The administration needs to "be honest with the American people," he said. "When I hear these dates, I believe they are as solid as quicksand."
