War Timetable

Some experts say waiting a little longer to go to war with Iraq would actually benefit our military, which still needs at least a few weeks to prepare for an all-out war.

"Right now, there is certainly a case for giving the Pentagon more time. They don't have anything close to all their forces in place," said Michael O'Hanlon, Brookings Institution.

Military leaders say 150 to 200 thousand U.S. troops would be needed for a war. That's double the current amount in the region.

A strike is unlikely until Februaryto Mecca concludes. March is looking to be the most favorable time, due to the climate and new moon.

The U.S. military would most likely utilize technology and do much of its fighting at night. Experts say the bulk of activity would need to be over by April, before the heat makes fighting more difficult and dangerous.
