John McCain has been on the campaign trail lying to Americans that his plan for the "surge," an escalation of American forces in Iraq, has been responsible for the reduced level of violence. George W. Bush keeps insisting things are on the road to victory though he fails to define what victory entails. They have so redefined and dumbed down their definition of "victory" it seems that a one hundred year military presence in Iraq means we win.
The truth is the decrease of violence in Iraq has been accomplished by Moqtada al Sadr, not the surge. The shia leader established a cease fire for his Mahdi Militia and extended it until recently when his militia increased its violence and the myth of the surge crumbled. Now American forces are using armored units to try and quell the violence.
Al Sadr controls the level of violence in Iraq, not George Bush, not John McCain. There is security there or isn't depending on his orders to his followers, not because Bush and McCain sent more American GI's. This week is visible proof of this as the militias are, again, engaged in violence and the lower levels of violence disappears.
