Reminds me of the 1970s novel THE CAMP OF THE SAINTS by JEAN RASPAIL

The Camp of the Saints (Le Camp des saints) is a 1973 French apocalyptic novel by Jean Raspail. The novel depicts a hypothetical setting whereby Third World mass immigration to France and the West led to the destruction of Western civilization. It sparked controversial reactions ranging from prophetic to discriminatory. Almost forty years after publication the book returned to the bestseller list in 2011.[1]
“THE CAMP OF THE SAINTS”
