True. And that is why America is disintegrating/dying now. It was designed to be a White Anglo-Protestant state. The principle and values of the Constitution/Bill of Rights have got Anglo-Saxon - Protestant - "Enlightenment" (John Locke). When, in 2020 you have 17 million African American and 61 million Hispanics who culturally speaking have no affinity, affection, genuine innate understanding or sincere respect for the principles/values/ideals of the Constitution and Declaration of Independence then the Republic of the US the Founders created, as you say, "Balkanizes" (racial groups never integrate, esp racial/ethnic groups so culturally disparate as America's White, Blacks and Hispanics), so the society fragments and deconsolidates. There is no such thing as America any longer. That is what we are seeing happen right now. The ultimate result will be a two-tier socialist Third World state like Mexico, where an elite super- wealthy Ruling Class governs oi polloi - a massive multi- race population of "serfs" who are the subjects of a powerful, corporatocracy (corporate Ruling Class billionaires +government).... or something along these lines. So, in short, you are right. America is dead, finished. Mass immigration starting in 1965 and neo- Marxist ideological subversion over the past six decades were what killed it.
