FAS (Federation of American Scientists) - Probably the best source of weapons technology data on the internet. The seem to be pretty accurate, although their agenda is a little to the left.
Pollingreport.Com - This site is not a poll site. Rather, it consolidates polls from a variety of sources (both liberal and conservative) into one place. This is a good place to go to find trends as well, since they have poll data going back years.
CIA World Factbook - A detailed database of every nation on the planet. Includes Geographic, Population, and political data.
Nationmaster.Com - Extensive trade and population database for dozens of nations.
Factcheck.Org - I use this site a lot too. They seem unbiased, and are very thorough. They include links to their sources as well.
Saddam's UN Violations - I know liberals wont care, but in case any conservatives want a list of the exact violations he committed, here it is.
Amnesty International's 1988 report on Iraq - In case anyone still has lingering doubts.
Sun Tzu's Art of War - An online version of the book, hosted by FAS.
Taiwan Relations Act - Online version of the TRA.
Aluminum Beanie - For all the conspiracy theorists on the forum...make sure you buy your's today.
