As long as the media doesn't takes side or make up its stories,
its not really a bad thing to have them around. They help remind
the troops that their actions are being watch by the world, how
they fight, how they handle prisoners, et cetra plays a great deal
to them who calls themselves professionals. 
Honestly, I think Rumsfield is Ooold! Due to the prisoner abuse
case & others, he does come across as being sleazy but the
truth is that he is hell-bent on getting this war started &
ended before he sleeps. So he is doing all he can to ensure that
this war will not be like, what everyone likes to compare, the
Vietnam war. And as we can see, its not easy. 
In a different view, if Rumsfield is appointed as Sec of State,
then America would be in deep crap. I guess thats why the Bush
didn't change Rumsfield appointment.
