[1] In part because of the book, CIA director William J. Casey commissioned a Special National Intelligence Estimate on Soviet support for terrorism.
Although Casey was advised that the CIA had played a part in supplying Sterling with "concocted misinformation for public propaganda", he requested that the draft be revised.

Sterling's conclusion is that the Soviets are not coordinating worldwide terrorism from some central point, but that they are contributing to it in several ways.
He was quoted in National Review, a conservative magazine, claiming that "Almost everything Claire said was borne out" by Stasi files that emerged after the end of the Cold War.
