The only way they have a hope of changing things is to stop by whatever means, any efforts by Islamic third world shitholes to educate or teach the people migrating to Europe.
I would impose the same on the Jewish as well. No more foreign influences on state education. Burn it to the ground.
Even in the US you have religious schools as well as international schools

No islamic studies and radical ideology should not be part of germany state classrooms but the banning of foreign schools could also lead to american, british, french and germany schools being banned around the world, including universities.
I took my GCE A's and O's and later attended an American University oversea instead of a baccalaureate but having the option for those working or living overseas is important.
The closing of the Madrasa was voluntary thankfully. I do think there should be some cooperation with what is taught in some madrasas because of radicalization. I don't think they should be outright banned.
I do think religious and foreign schools should be private not state funded. Scholarships are an option.
Many muslims used to sent their children to christian schools, but when Hezbullah interfered I strongly disagree with. They took the school hostage to force the dress code that all parents and student had agreed to, to change where by muslims girls had to wear the hijab in classes and on campus. Rome finally relented after a number of weeks, at least for the one school.
I've also seen girls beaten for walking out of school without the hijab in hezbullah areas, and parents for trying to interfere.
I'd hate to have had to go to school in a madrasa just because I lived overseas.
