It's basic culture warfare and it's been happening for decades. Listen to some Yuri Besmenov [1] if you don't know what I'm talking about. Basically my point is they don't care, because any division in their enemies is a good thing for them. While they retain immense strength and nationalism.
I'll give you an example of poisoning the well. So many dual-citizen self admitted Zionists in America and Europe are pro-refugee. They adamantly fight for more refugees in these host countries. However their home country, Israel. Is entirely anti-refugee to a shocking degree.
It's all part of the same pie. Marxism, communism, feminism, egalitarianism. Destruction of western civilization.
