People are who they are because of what they have been through, where they came from, who they learned from, and all the things that have happened to them. The same is true not just for individuals, but also for families, communities, and nations. America, too, has its own unique character, also formed by its memories, history, things it has been through, and what it has learned.

If people, communities, or even nations lose their memory, they lose their character. That is why cultures throughout the world work at maintaining their identity and passing traditions along to future generations. But what if a nation purposely decides it no longer wants to remember its history? What if a country imposes amnesia on itself?

Helen Krieble argues persuasively that this is precisely what has happened to America. It has lost the memory of its own founding principles, and the sacrifices made over the past 250 years to preserve them. The nation is losing its character. She writes that America cannot be preserved as "the last best hope of Earth" if its own people no longer understand why that is true and are no longer willing to do what it takes to preserve it.

"The duties of citizenship are vitally important," Krieble writes, "but they are not complicated. It is our duty, as the owners, to defend our freedom against all threats, and to pass it along to future generations undiminished."

Americans are failing in that duty, but Krieble says there is still time to cure our national amnesia. It begins with rebuilding our understanding of, and commitment to, those founding principles, regaining our national memory.
