A growing number of Americans want to tear down what it’s taken us 250 years to build—and they’ll start by canceling our shared history, ideals, and culture. “Disintegrationists” say we’re stronger together, but their assault on America’s history, philosophy, and culture will only tear us apart. Disintegrationist attacks on the values that built our nation are insidious because they replace each foundational belief with nothing more than an increased reliance on the government. This twisted disintegrationist vision replaces the traditional “unionist” understanding that all Americans are united in a shared striving toward the perfection of universal ideals. Shapiro shows that to be a cohesive nation we have to uphold foundational truths about ourselves, our history, and reality itself—to be unionists instead of disintegrationists. Shapiro offers a vital warning that if we don’t recover these shared truths, our future—our union—as a great country is threatened with destruction.
