I once had a conversation with a 1980's era cold war intelligence agent. It was known that the then powerful Soviet Union had contingency plans to invade the USA. The Russians felt confident that they could defeat our then military. What kept this from becoming a viable option was and I quote what a soviet spy told him "You Americans have too many $%#@ing guns". Yes, they were more afraid of American citizens than the US military. I have always been glad he shared this with me. Gives me a deeper meaning of how brilliant our fore fathers were and the importance of never forgetting what it means to be free and what it takes to stay that way.
