Before the sixties, America was 90% white and had an immigration policy that, while allowing for some non-white immigration, strongly favored white immigration. This was purposely done to keep America as white as reasonably possible. That is how America was an ethnostate.
Jews want every country they occupy (except Israel, of course) to be multiracial because it makes it easier for them to gain power.
Jews function as a state within a state, hording wealth within their own community, which greatly harms the economy of the host country. This is why the Jews have been kicked out of over a hundred countries. In most cases, before the Jews were kicked out, there was a Nationalist uprising. The people noticed that the Jews, this tiny minority, were hording wealth. It's because of this, that Jews are terrified of Nationalism that isn't their own. This is why they use their positions in the media and academia to promote White Guilt, mass immigration, and Globalism. It's also why they supported and promoted Communism. If countries like America become multiracial, then suddenly there is nothing suspicious about a minority making up most of the 1%. That's how Jews were able to take over the Soviet Union.
This also gives the Jews an advantage because while they're sticking together, fighting as a team, white people aren't doing the same. We've become extreme individualists, which puts us at a disadvantage.
I think there also might be some jealously involved. Jews have never been able to build a great society on their own, despite being told they're God's chosen people. So it's possible they want to take over our societies to both stick it to us, and reassure themselves that they are the master race. This also goes for Atheist Jews who have the culture of Judaism.
TL ; DR - Jews are afraid of Goy Nationalism, know that being Nationalist in a Globalist country gives them a huge advantage, have a vendetta against the white countries, feel they should rule over the Goys.
