"Think tanks provide a steady stream of experts to serve in incoming administrations and on congressional staffs," a function that is "critical in the American political system," says State Department Director of Policy and Planning Richard Haass. In addition, he says, "think tanks provide departing officials with institutional settings in which they can share insights gleaned from government service" and "remain engaged in pressing foreign policy debates."
