Supposing Jay Garner hadn't been fired and L Paul Bremer wasn't put in charge of the Coalition Provisional Authority? Might there have been elections in July 2003? The local elected governments not dissolved? Might debaathification not have happened?
If any of this had happened -- how would the Iraq War have progressed differently? Would the length of US military involvement have been lessened, shortened? If elections were held while Saddam or his sons were still at large, how might that have changed things? And what else might the butterflies have in store?
