The Bush administration, however, already has crossed other bright lines of international law, including the invasion of a non-threatening foreign nation and complicity in torture, such as subjecting captives to simulated drowning in a process called "water-boarding."
So, how unthinkable is it really that the Bush administration might venture across another boundary of civilized behavior?
What if Iraq's Sunnis dig in their heels because they suspect that their historic Shiite rivals plan to deny the Sunni population a significant share of Iraq's oil reserves, which are located mostly in Shiite and Kurdish territories?
If that's the choice the Sunnis make - and if Bush sees his commitment to a "complete victory" as part of God's plan - might the Shiites then exploit U.S. air power to inflict a final crushing blow against their ancient enemies?
Perhaps cooler heads will prevail and excessive bloodshed will be averted. But if too many more lines get crossed, the rest of the world may extend the list of crimes already blamed on the Bush administration - to include genocide.
