The problem with these tapes are that they cover about 12-1/2 years, and there is a gap, naturally, around 1999 - 2002. (I was 1/3 asleep when I heard this last night, so some details could be off a bit)
These tapes should make it clear Saddam was actively playing hide and seek with WMD's and playing the weapon inspectors for fools.
I think that everyone needs to realize that by talking about these tapes ABC is actually doing damage control for the left. Moments ago on their radio news, they made a huge point to claim that the tapes suggest that Saddam was innocent of any aggressive intentions against the US.
Other MSM outlets will soon be able to say, "old news, nothing new."
