The Federation of American Scientists (FAS) is working on issues of global security, the environment, democratic governance and human rights. FAS continues a commitment to informing the public debate on complex scientific and technical questions. We are dedicated to "speaking truth to power" -- representing the public interest and defending against the special interests. We don't get any money from the government or large corporations, but we do spend a lot of time and money making our web resources available to the public. If you have found our web site useful, please help us continue to provide this resource. Please support our shareware implementation by making a tax-deductible contribution -- in any amount -- to our policy research and education arm, the FAS Fund.
