Blackwater USA, the US Private Military Firm (PMF) changed its name. It is now going to do business under the brandname Xe. The rebranding reflects the bad reputation the firm earned operating in Iraq, as a result of killing civilians.
The firm was the number one PMF used by the USA to fight the insurgency against their occupation of the Middle Eastern country. It was responsible for the security of the State Department Staff in Iraq including governor Paul Bremer and his successor John Negroponte.
The US heavily depends on personel provided by PMFs in its struggle against terrorists motivated by Islam, who are waging Jihad on the USA and other Non-Islamic nations.
