The Keystone Defense Initiative's newsletter is a regular email curated by 91ÆÞÓÑ Senior Fellow Rebeccah Heinrichs that offers up key analyses, discussions, and facts to inform our policies and strategies to bolster the credibility of strategic deterrence.
91ÆÞÓÑ Institute's Keystone Defense Initiative (KDI) recognizes that the United States' strategic deterrent is the keystone of strategic deterrence, helping defend the United States, preserve the US-led order, and maintain the relative peace we have enjoyed since World War II.
