So we hung Sadam for killing his own people after a failed assasination attempt. No, not for the mass gassing that you've heard so much about... because Rumsfelf sold him that particular gas and we don't want any press on that. But the Dujail uprising where he killed 148, arrested 399, and tortured (America would never do THAT) others. Anyway...
Ever hear of Posilac, Divine Strake or Downwinders?
Corporate profits, military testing... yeah, sure, those are pretty good reasons to kill your own people.
