The Bush Doctrine resulted in criticism and controversy. Peter D. Feaver, who worked on the Bush national security strategy as a staff member on the National Security Council, said he has counted as many as seven distinct Bush doctrines. One of the drafters of the National Security Strategy of the United States, which is commonly mistakenly referred to as the "Bush Doctrine," demurred at investing the statement with too much weight. "I actually never thought there was a Bush doctrine," said Philip D. Zelikow, who later served as State Department counselor under Secretary of State Condoleezza Rice. "Indeed, I believe the assertion that there is such a doctrine lends greater coherence to the administration's policies than they deserve." Zbigniew Brzezinski, Jimmy Carter's national security adviser, said he thought there was no "single piece of paper" that represents the Bush doctrine.
