Quincy Institute for Responsible Statecraft
Initial funding for the group, launched in November 2019, includes half a million dollars each from the Open Society Foundation (George Soros) and the Koch Foundation (Charles Koch).
The think tank is named after U.S. President John Quincy Adams, who as Secretary of State said, in a speech on July 4, 1821, that the U.S. "goes not abroad in search of monsters to destroy". It has been described as "realist" and advocating for "restraint" in orientation.
