Where is the scientific, historic or empirical evidence that the greater the racial, ethnic, cultural and religious diversity of a nation, the stronger it becomes?

From recent decades, it seems more true to say the reverse: The more diverse a nation, the greater the danger of its disintegration.

Ethnic diversity, after all, tore apart our mighty Cold War rival, splintering the Soviet Union into 15 nations, three of which — Moldova, Ukraine, Georgia — have since split further along ethnic lines.

After playing clips of Democratic politicians reciting “Our Diversity Is Our Strength”, i.e., that so-called truth of modern liberalism, Tucker Carlson asked, “How, precisely, is diversity our strength? Since you’ve made this our new national motto, please be specific.”
