American Big Oil. Their greed today far pales such of the past robber barons of steel and train transport rail systems. Their rolodex has numbers of those who can make any obstacles threatening their profits disappear.....forever--without any traces.



American Big Oil's greed is an insatiable hunger that if not controlled and fast--may very well cause global economic damage that'll put us in a depression 10 times more severe than the '20's stock market debacle.



American Big Oil is out to show us they, not the President, runs America. Question is: are we gonna sit helplessly by and let them?
The US government
most do about the same thing...just because one group may have killed 2 more than another doesnt make them any more stronger or more ruthless. i wouldnt say any one ocs but all.but if i had to take a pick i would say...

italian/mexican mafia...the triads are very ruthless but you never hear about them here...mostly just italian and mexican.



as far as street gangs...it would be crips.why?theres more of them than bloods. but the mexican gangs are pretty big as well but here in my state the crips out number them all. (maybe not in cali or texas)
The Catholic church aka Holy Roman Empire.
I would have to agree with the bush admin. answer.
The russian mafia , The D company and at last but not the least , the inventors of suicide bombers The LTTE
Has anyone mentioned the Illuminati yet?
MS-13 has climbed to the top of the list in the last few years.

I have a buddy that works for the Dept. of Homeland Sec., He tells me that your typical street gangs are now categorized as tarriest organizations. He also stated that the gangs like the Crips and Bloods look like a bunch of little sissies compared to these guys.
