According to the news item, what is expected from Obama’s announcement? [br] [o

In a speech this evening, President Barack Obama is expected to announce a gradual withdrawal of thousands of American troops from Afghanistan. Early reports suggest they’ll be withdrawn in phases with around 5,000 troops leaving within months. Jonny Dymond in Washington has more.
    The enormous cost of the military deployment, currently more than $ 2bn a week, is attracting high-profile criticism from Republicans and Democrats whilst the public, battered by hard economic times, are weary of a war that seems to have no end and appears punctuated only by the deaths of young Americans. But the president cannot cut too deep or too fast. His military commanders are wary of throwing away hard-fought gains by withdrawing troops too soon.
