Good article on Slate regarding the DSM and DSM-II.
http://slate.msn.com/id/2120886/Unfortunately they don't find them that strong, but they do make some good conclusions (and let more of the public know about them). Excerpt:
In other respects, though, the memo doesn't make as strong a case against Bush as some have claimed. Read in conjunction with the six other British documents, the case weakens further.

In fact, the memos reveal quite clearly that the top leaders in the U.S. and British governments genuinely believed their claims.
