Someone posted that these mercs "are human beings". So are Saddam, Bush, Kissinger, Cheney, Chalabi and many others that have chosen to kill, if necessary, for massive wads of cash.
Most mercs are there protecting oil wells and fuel convoys for Halliburton and the rest of the corporate elite. You know, those fat fuckers in gray suits drinking scotch, smoking cigars and planning the next war for cash.
To me, most mercs aren't much different from the engineers working at Lockheed Martin and Boeing on projects centered around how to kill more people more efficiently.
Why do we see so much terror in certain regions? Because fucking arms dealers are making their fucking killing implements available to fucking cretins that believe in a fucking cause enough to kill a bunch of innocents.
Where are Palestinians getting the bomb making materials for their suicide attacks? Where are the IED's in Iraq coming from? How 'bout the assault weapons and RPG's used in the atttacks in Fallujah? This shit is manufactured and sold by, among others, American arms manufacturers and American arms dealers.
Oh, and btw... who do you think runs these guns, explosives and other death tools? Fucking mercs.
