Here's an intesting quote:
"...Defense Secretary Donald H. Rumsfeld, who headed a commission in 1998 warning about missile threats from North Korea and Iran, says a defense is vital. It isn't. As Greg Thielmann, the director of the State Department's Bureau of Intelligence and Research during Bush's first term, has written in Arms Control Today, Rumsfeld contorted the evidence in 1998 to create a North Korean and Iranian missile threat to the United States where none existed, just as he would later do on the issue of Iraqi weapons of mass destruction.
It's unfathomable how Bush can continue to talk about the need for spending cuts while embracing one of the least successful and costliest military research programs in recent memory."
