There is no shortage of Jews and especially rabbi's over the years taking credit for the mass migration into every western nation. Some will speak with absolute glee over the state of the west. It is viewed as the new rome. As Edom as they call it. You'll see it chalked up to anti semitism to call it out, but we live in a time where quoting them is anti semitic.
So I'll go ahead and summarize it for you. In order for their Messiah, or mechiach to come about, the Christian world, or western world, needs to fall. Mass migration especially from Islamic nations is a means to that end. Jews prefer Muslims over Christians, regardless of what you've been lead to believe because they see Muslims as truly monotheistic unlike Christians.
You should also look into the noahide laws, which discussions have been renewed, and there is a meeting taking place this November. Christianity is considered idolatry which violates the very first law, and violating any of the noahide laws is punishable by death via beheading.
