Bush set out the operating parameters here: We will, whenever possible, minimize casualties to Iraqi citizens and vital infrastructure. That was part of a political calcualation, understanding that we're going to be mucking around in that hellhole for a while and since we have the tools of accuracy and timing, we'll use them.
Rumsfeld, Franks and the management council came to Bush when the opportunity to vaporize Saddam in his flop house materialized that first night. That was a material and profound change in the plan the Prez authorized. If bombing a hospital would achieve an unarguable and vital operational objective ... they would probably run that by the Joint Chiefs and Rumsfeld first, then Bush. That's a tough tradeoff, it comes into conflict with the operational parameter of rules of engagement, and that warrants the Big Boy's attention and approval or squelch.
Rescuing a fellow soldier when the time is ripe is not something the CIC needs to authorize. He doesn't have to be in the loop if the Charmin is going to the Marines and the Army is going to be pissed because they get the Puffs two ply again. Bush is not interested in the Geraldo Rivera crisis one iota, and Maureen Dowd's heartsickness for Michael Douglas can't make him laugh like it used to.
These reporters hear nothing. They are at press conferences to make statements and present challenges and fodder for feeling doubtful, fearful and uncertain about this President and our campaign.
