One Percent Doctrine

Here is an excerpt of the review for The One Percent Doctrine by Ron Suskind in The New Yorker:

In November, 2001, Suskind writes, Vice-President Dick Cheney announced that if there was "a one percent chance" that a threat was real "we have to treat it as a certainty in terms of our response." He added, "It's not about our analysis, or finding a preponderance of evidence."

Should I assume that he is talking about environmental threats? Should the United States devote more time and money towards the environmental threats that have been analyzed and highly corroborated by scientists? One would hope the threats that have been analyzed, or found to have a preponderance of evidence, would not be excluded while speculative threats are included.
