The US think tanks sit at the crossroads of the academia, politics, business, media and government and their associates frequently switch careers between these realms. They are the brokerages of research to support and push positions that ultimately may become governmental policies. With a massive growth in their numbers and clout over the last several decades, the US think tanks are of interest to anyone who will be affected by the US policies. While overlapping closely, and at times working with the academia, the think tanks are not exactly the ‘universities without classes’ that some of them claim to be. Most think tanks have tax exemption/benefits under the US tax code but are not mandated to disclose their donors publicly. While all donations over $5000 are reported to the government (IRS Form 990) many think tanks also voluntarily make their donors’ lists public. However, unlike the academic research the disclosures are neither full nor forthcoming in many cases and, as Ken Silverstein of The Nation, USA, pointed out in his May 2013 report on secret donors of the think tanks, ‘it’s not always easy to see what sort of benefits money can buy.’
