You did use another quote, saying, “Never say never” with respect to policy decisions and alliances and those sorts of things. I'd like to ask you for a moment about the decision not to participate in ballistic missile defence.
Certainly, the multi-generational history we have on continental security through NORAD has us as a full partner in 95% of NORAD operations, with the exception of BMD.
Could you explain the rationale for not participating in BMD when you were in cabinet?
