We should take heed from past empires and countries that were great at one time. Nowhere is it foreordained that America has a birthright to remain the world's preeminent civilization. China believes that America is decadent,undeserving of its affluence,living beyond its means on the fumes of the past-and very soon vulnerable enough to challenge openly. We seem to hate each other more than we do our common enemies. We think we're invincible but our military is more worried about being "woke"than deadly. Americans have become snarky iconoclasts tearing down our past. I hope we wake up in time to care.
