You may also know that Cheney was secretary of Defense under George H. W. Bush, and a congressman from Wyoming.
But you may not know that -- in the 70's -- Cheney was instrumental in generating fake intelligence exaggerating the Soviet threat in order to undermine coexistence between the U.S. and Soviet Union, which conveniently justified huge amounts of cold war spending. See also this article. This scheme foreshadowed Mr. Cheney's role in generating fake intelligence in Iraq by 30 years.
And did you know that Cheney has been perhaps the leading advocate for strengthening the powers of the White House to the point of monarchy for at least 20 years?
Or that newly-released documents show that Cheney was involved in debates concerning illegal wiretaps 30 years ago?
And, according to to the Pulitzer prize-winning reporter who uncovered the Iraq prison torture scandal and the massacre against Vietnamese civilians, Cheney is the main guy helping to fund groups which the U.S. claims are terrorists (see confirming articles here and here)
And guess who is the prime architect of efforts to bomb Iran? Yup, Mr. Cheney (see also this article).
To recap, Cheney's past includes:
• Faking intelligence and using scare tactics about enemies to justify a pre-planned military agenda
• Calling for an American empire and lamenting the lack of a "new Pearl Harbor"
• Police state type wiretapping
