WASHINGTON (AP) - Sen. John McCain is dropping his threat to block Gen. Martin Dempsey's nomination for a second term as chairman of the Joint Chiefs of Staff.
But the Arizona Republican delivered a harsh critique Tuesday of Dempsey's assessment of potential American military action in Syria.
McCain called Dempsey's evaluation, outlined in a letter Monday to Sen. Carl Levin, "most disappointing" because the general described a scenario where it is impossible to intervene.
Dempsey wrote that establishing a no-fly zone to protect Syrian rebels would require hundreds of U.S. aircraft at a cost as much as $1 billion per month and no assurance it would change the momentum in Syria's civil war.
McCain says he won't stop Dempsey's nomination because President Barack Obama has the right to choose the team around him.
