From the Washington Post:
President-elect Barack Obama intends to sign off on Pentagon plans to send up to 30,000 more U.S. troops to Afghanistan, but the incoming administration does not anticipate that the Iraq-like "surge" of forces will significantly change the direction of a conflict that has steadily deteriorated over the past seven years.
P.S. See this Jim Geraghty post for Obama's changing assessments of the usefulness of 30,000 U.S. troops.
