Here's a crazy thought. How about enforcing the law?
"The money is increasingly transforming the once-staid think-tank world into a muscular arm of foreign governments' lobbying in Washington. And it has set off troubling questions about intellectual freedom: Some scholars say they have been pressured to reach conclusions friendly to the government financing the research.The think tanks do not disclose the terms of the agreements they have reached with foreign governments. And they have not registered with the United States government as representatives of the donor countries, an omission that appears, in some cases, to be a violation of federal law, according to several legal specialists who examined the agreements at the request of The Times.As a result, policy makers who rely on think tanks are often unaware of the role of foreign governments in funding the research."
My favorite trick is when the hawks in Congress appropriate money to foreign groups, such as the Iraqi National Congress, or shady opposition groups in Iran, who then funnel the money back into lobbying the US government and propagandizing in the US. Like a perpetual motion machine for foreign adventurism.
