WASHINGTON (CNN) - President Barack Obama will likely make a decision on sending additional troops to Afghanistan "in the course of the next few days," Defense Secretary Robert Gates said Tuesday.
"I think that there is a realization that some decisions have to be made ... before the strategic review is completed," Gates said at a news conference. "He has several options in front of him."
Gates, one of three Republicans appointed to Obama's Cabinet, said the administration will wait until a strategic review of military operations in Afghanistan and Iraq is complete to make decisions on "the strategies going forward."
"I worry a lot about the foreign military footprint in Afghanistan ... I think and I hope that the strategic review that is underway will sort of point a path forward in terms of what we think the right number, the right size of the foreign military presence in Afghanistan should be," Gates added.
On Sunday, two senior Pentagon officials told CNN that decisions about withdrawing troops from Iraq and sending more troops to Afghanistan have been delayed until the Pentagon provides Obama with more detail about the risks and implications of the issues confronting him.
Both officials, who asked not to be named because of the sensitivity of the issue, have a direct understanding of the discussion regarding troop withdrawals. They said the military is not concerned about the delays, but that there is concern about the deteriorating levels of security in Afghanistan.
It is believed that thousands of ground combat Marines, a marine aviation unit and Army special forces could be sent to southern Afghanistan in the weeks ahead. The officials also confirmed that the Pentagon and U.S. Central Command are now working on three Iraq combat troop withdrawal options for the
president: 16 months, 19 months and 23 months.
Given the current security situation in Iraq, the United States can likely reduce troop level from 14 brigades to 12 by the end of the year, the
Also Tuesday, the defense secretary addressed a newly released Pentagon report showing Army suicides dramatically up this year. The Army reported that 24 soldiers are believed to have committed suicide in January alone - six times as many as killed themselves in January 2008, according to statistics released Thursday.
If all those prove true, more soldiers will have killed themselves than died in combat last month. According to Pentagon statistics, there were 16 U.S. combat deaths in Afghanistan and Iraq in January.
Gates told reporters that the military has put a lot of effort into helping troops and their families - and said the strain of long deployments is causing much of the stress.
"I think part of the problem in terms of the strains ... whether it's divorce rates or suicides, I would say ... these are manifestations also of repeated tours," Gates said. "It's not just the length of the tour, but the fact that so many have gone back for two or three, even four rotations in Iraq and Afghanistan. I think it's a combination of all those things."
Joint Chiefs of Staff Vice Chairman Gen. James Cartwright, also at the press conference, said the suicide and divorce rates would come down as the tours are reduced.
"That's another benchmark we've got to cross before we can expect to see some of these rates start to move in a positive vector. But I think the bigger issue here is the cumulative effect," he said. "We've got work to do ... we're watching this very closely."
