The Think Tank Method
Still some are located on the campuses of esteemed educational institutions, like 38° North, the North Korea policy team, which enjoys an association with John Hopkins University.
The Rand Corp is a defense department-related private sector group founded by Air Force General HH Arnold after WW2, and is primarily dedicated to foreign policies that include war, as well as the research and development of defense-related issues.
It is through the Rand Corp that right wing agendas are often planned. They design the actual war, and strategy of any given war, consulting on every defense related issue.
The fact that the right wing and left wing use these think tanks in the same way speaks to how they remain allowed to operate.
Nixon simply kicked the AG out of the loop. He then ordered the Watergate Democratic Party HQ to be the target of a break in. But that is just one testament of the effect that these organizations have in DC, that Nixon was willing to risk murder and arson charges, to, as he believed, eliminate the, "Brookings people" from succeeding in their plot to, "de-throne" him.
Most political scientists had agreed with the founder of presidential character assessment, David Barber. Barber, in 1969, had predicted that, "Nixon will be in trouble by his second term."
But Nixon's undoing came not from the Brookings Institute, but, instead, it came from a leaker, Daniel Ellesburg, and his publication of the Pentagon Papers, a set of memos, studies, and outlines that prove the power elite knew that the Vietnam Conflict was unwinnable, but kept escalating the intensity of the conflict, anyway. The fact that Ellesburg worked for the Rand Corp, and not the Brookings Institute, means that Nixon knew what street to look down to find his "enemy", he just had the incorrect address.
The Brookings Institute consults on issues considered progressive, which are considered by many to be a threat to the vitality of the nation; and pursues these agendas by acting as a parent company to affiliated organizations which share this agenda.
There are a variety of ways which the government does its dirty work through the think tank method:
Through his Open Society Foundation, George Soros acts as a US Diplomat staking foreign officials and warlords with cash which would place the ordinary citizen, as well as the US elected officials that initiate these methods, into jail. Cash is "donated" to the Open Society Foundation, from the Federal Reserve via tax exemption, which, then, funds failed coup attempts against Erdogan in Turkey, or the notorious White Helmets in Syria: whom forged gas attacks in convenient ways for NATO to both pretend to fight, but in reality, support ISIS.
