Lee Kuan Yew's 2013 Forbes interview about America and multiculturalism : Did LKY warn then that the riots America is facing today were inevitable?

Senior Minister Lee Kuan Yew of Singapore

In 2013 Forbes published an interview with Lee Kuan Yew. Headlined  Singapore's Lee Kuan Yew Talks America's Strengths And Weaknesses Lee was reported to have said:

Lee warns about the growing risk of America’s losing its “self-help culture” and going “the ideological direction of Europe.” If it continues that slide, he says bluntly, “the U.S. will be done for.” He also gives U.S. immigration practices a failing grade, declaring that “multiculturalism will destroy America.” The key question is: “do you make the Hispanics Anglo-Saxons in culture or do they make you more Latin American in culture?” 

The violence that is being witnessed in America today, even if initially a protest over police violence against blacks, is now obviously about a desire for "change" ie toward the “multiculturalism (that) will destroy America.”
Did then Lee leave unsaid that the conflict will be violent. On the hand, should it not have been assumed that he meant violent conflict?
