WASHINGTON -- President Barack Obama will announce Wednesday the critical next phase in America's decade-long war in Afghanistan, defense officials said, outlining both a plan to start bringing U.S. troops home next month and a broader withdrawal blueprint aimed at giving Afghans control of their own security in 2014.

But even as Obama nears a decision, there are deep divisions in his administration. Military leaders favor a gradual reduction in troops but other advisers advocate a significant decrease in the coming months.

Administration officials say Obama is still deciding how many U.S. troops will start leaving Afghanistan in July, his self-imposed deadline for beginning the drawdown. He is considering a range of options from Gen. David Petraeus, the top U.S. and NATO commander in Afghanistan, and is expected to announce his decision this week. He is to visit troops Thursday at Fort Drum, the upstate New York military base that is home to the 10th Mountain Division, one of the most frequently deployed divisions to Afghanistan and Iraq.

"He's finalizing his decision. He's reviewing his options," White House spokesman Jay Carney said yesterday. He said Obama's announcement would be soon.

While much of the attention is focused on how many troops will leave Afghanistan next month, the more telling aspects of Obama's decision center on what happens after July, particularly how long the president plans to keep the 30,000 surge forces he sent in 2009 in the country.

There is a growing belief that the president must at least map out the initial withdrawal of the surge troops when he addresses the public. But whether those forces should come out over the next eight to 12 months or slowly trickle out over a longer time is hotly debated.

Military commanders want to keep as many of those forces in Afghanistan for as long as possible, arguing that too fast a withdrawal could undermine the fragile security gains in the fight against the Taliban insurgency in Afghanistan, the al-Qaida training ground for the Sept. 11, 2001, attacks. There are also concerns about pulling out a substantial number of U.S. forces as the heightened summer fighting season gets under way.

Retiring Defense Secretary Robert Gates has said he believes the initial drawdown should be "modest."
