Think tank partnership are increasingly common, as Think Tank Watch has documented, but to have that many partnerships is almost unheard of.
The Stimson Center was just ranked as the 24th best think tank in the world by the University of Pennsylvania think tank rankings.
In October, Brian Finlay became the new president and CEO of the Stimson Center. Former President Ellen Laipson became a Distinguished Fellow and President Emeritus after serving more than 13 years as the think tank's President and CEO.
