Killing Al-Zarqawi not a "success"

I wish the damned conservative pundits would stop pointing to the killing of Al-Zarqawi as a "success" in Iraq. He would not have even appeared on the radar as a threat if it had not been for America's invasion in the first place. He only came into being as a leader of the terrorist insurgents in Iraq after we went in and painted a big bull's eye on the country. This is the equivalent of turning a tenant house into a slum and then indicating how good it is that you are there because you killed a rat. Or turning a river into a sesspool and then showing how good a job you are doing by cleaning up one pollutant.
