Clash of CulturesThe debate continues in the U.S. on whether or not we should build a wall to enforce immigration laws and protect our borders. I stood at a section of the U.S.-Mexican border protected only by a rusted barbed wire fence overgrown with cacti. A Border Patrol officer told me that dope smugglers, human traffickers, gangsters, terrorists, and illegals of various stripes swarm like cockroaches across border areas like this one as soon as the sun goes down. There is nothing to stop them.

Border enforcement officers almost unanimously support building a wall as a barrier. On the other hand, the “open borders” and “sanctuary cities” mobs charge that it is “immoral” to prevent anyone in the world from coming into America if they want to come. Besides, they claim, walls don’t work.

I’ve traveled the globe as soldier, war correspondent, adventurer, and journalist for nearly 60 years. I’ve seen where walls work in Israel, Eastern European countries, and elsewhere. I’ve witnessed atrocities, crimes and terrorism where borders are not enforced—in Algeria, Honduras, El Salvador, Colombia, in France, England, Germany, the United States. . . The list goes on and on in a clash of cultures that can only end in disaster.

Cultural, moral, and economic decay within a society eventually leads to invasion when the civilization is no longer able, or is unwilling, to defend itself and its borders. Political leaders in the U.S. beginning in the 1990s have not only permitted such transgressions but have assiduously promoted them by bowing at the altars of “diversity” and “multiculturalism.”

E Pluribus Unum—“Out of Many, One”—is no longer relevant when immigrants, legal or otherwise, openly challenge the culture they invade by refusing to assimilate and instead adhere to and propagate the values, customs, language, and culture of their home societies. This eventually produces internal strife, dissension, and further deterioration of the host.

“The one absolutely certain way of bringing this nation to ruin,” warned President Theodore Roosevelt, “of preventing all possibility of it continuing as a nation at all would be to permit it to become a tangle of squabbling nationalities.”

A nation lacking a common cultural core and language cannot long endure. At the rate of its deterioration, the U.S. my soon become the last anomalous holdover for a fading Western world.

What fools these mortals be.
