Of all the dangers facing our country, perhaps the greatest danger of all is the one that still doesn’t make many headlines — our collective national amnesia. Our history textbooks are sanitized to be politically correct and give our children little sense of the greatness of the nation they live in. The Founders are seldom mentioned unless it is part of a controversy about slavery or some other scandal.

I am often struck by how often decent American kids have nothing good to say about their own country. Their knowledge of the sacrifices made to establish and preserve their freedom is virtually non-existent. They are the recipients of the greatest freedom and opportunity that any society has ever produced, yet they are unaware of the price in flesh and blood that was paid for it.

At my father’s table, I learned love of country in a way that only a Marine could teach it. Dad taught me that patriotism wasn’t a theory — it was flesh and blood, real sacrifice and pain. You are your children’s most important teacher. They are listening.

This weekend, as we celebrate Memorial Day, tell your children about the sacrifices that had to be made to stop the march of fascism and the cancer of communism. Tell them about the beaches of Normandy and the Bataan Death March. Tell them about why there was a Berlin Wall and how free men brought it down.

Remind them about 9/11, what happened at the Pentagon and over the fields of Shanksville, Pennsylvania. Take just a minute in the next three days to teach them to love the things we love and honor the things we honor.
