American Mercenaries in Iraq

5 American Mercenaries were abducted and killed in Iraq this week. They neither are civilians nor they belong to the US Army. The Bush Administration had hired (a conservative estimate) 48,000 American Mercenaries who are not accounted for their actions in a combat atmosphere.
In the State Of Union Address on 23rd January, Bush had stressed for an increase in the number of soldiers to Iraq and also to raise Civilian Reserve Corps. This is nothing bu hiring mercenaries.
Is the US conducting a "War on Terror" or "Creating Terror" ??
