Repeatedly breaking int'l and domestic law, as well as the Geneva Conventions, unprovoked, Bush & Co. invaded and occupied two sovereign nations, killing over a million people in the process. They openly condoned and used kidnapping and torture as standard procedure, as well as weapons banned from the battlefield (depleted uranium, cluster bombs). Murder by torture was no doubt involved. Trillions in national treasure were looted and given to their cronies in the oil and defense industries; thousands of US lives lost and destroyed to enrich very few men.
Yet the first thing Obama did, in the name of "Moving Forward", was assure that these atrocities would go uninvestigated, let alone prosecuted, thus removing any moral high ground America may once have had in the world. Fix this, now.
