WEST POINT, N.Y. (AP) - Declaring "our security is at stake,"
President Barack Obama ordered an additional 30,000 U.S. troops
into the long war in Afghanistan on Tuesday night, but balanced the
buildup with a pledge to an impatient nation to begin withdrawing
American forces in 18 months.

In a prime-time speech at the U.S. Military Academy, the
president said his new policy was designed to "bring this war to a
successful conclusion." The troop buildup will begin almost
immediately - the first Marines will be in place by Christmas - and
will cost $30 billion for the first year alone.

"We must deny al-Qaida a safe haven," Obama said in
articulating U.S. military goals for a war that has dragged on for
eight years. "We must reverse the Taliban's momentum. ... And we
must strengthen the capacity of Afghanistan's security forces and
government."

The president said the additional forces would be deployed at
"the fastest pace possible so that they can target the insurgency
and secure key population centers."

Their destination: "the epicenter of the violent extremism
practiced by al-Qaida."

"It is from here that we were attacked on 9/11, and it is from
here that new attacks are being plotted as I speak," the president
said.

It marked the second time in his young presidency that Obama has
added to the American force in Afghanistan, where the Taliban has
recently made significant advances. When he became president last
January, there were roughly 34,000 troops on the ground; there now
are 71,000.

Obama's announcement drew less-than-wholehearted support from
congressional Democrats. Many of them favor a quick withdrawal, but
others have already proposed higher taxes to pay for the fighting.

Republicans reacted warily, as well. Officials said Sen. John
McCain, who was Obama's Republican opponent in last year's
presidential campaign, told Obama at an early evening meeting
attended by numerous lawmakers that declaring a timetable for a
withdrawal would merely send the Taliban underground until the
Americans began to leave.

As a candidate, Obama called Afghanistan a war worth fighting,
as opposed to Iraq, a conflict he opposed and has since begun
easing out of.

A new survey by the Gallup organization, released Tuesday,
showed only 35 percent of Americans now approve of Obama's handling of the war; 55 percent disapprove.

"After 18 months, out troops will begin to come home," he said
flatly.
