The term is not the best at all for the thought Bush was trying to con-vie
There are many that live under tyranny that do not agree with the dictator, but who are not willing to speak up. Sharansky terms them "double-thinkers" to distinguish them from the dissidents and the "true believers" who agree with the dictator.
The double-thinkers could be described as "simmering" I think.
But do you really think Bush was being that Nuanced?
