The palaces should have been bombed to smithareens by now. We have to get rid of as many suspected sites as possible before troops go in. It is suicide to let these bio and chemical sites exist before the invasion.
(I personally assume that we will attack all of their known scud sites and artillery emplacements with something akin to timed fire--calculated to impact all at the same time. It's the warheads and shells which are already readied and/or loaded--not the stockpiles or production facilities--which we need to worry about first. We can take out the suspected stockpiles and production sites right after that.)
