I am gonna ask the German state attorney I know what his take is on that next time I speak to him. But from my view, yeah that could already be a crime

In the case of the EU however as well as a bunch of European countries, DEI is literally part of the constitution. But hey, Dump and his team would need to inform themselves on other countries to know that
In German penal law there were discussions on how to treat those that act under orders. Many Germans did act under orders and even in accordance to law in WW2 but also in regard to the Mauerschützen (the soldiers that shot dissidents at the inner German border)- meaning that there were difficulties persecuting them as it was technically legal. There were way too few persecutions, however something called the Radebrechtsche formula was developed. Paraphrasing it says, something that is morally wrong to every morally thinking being cannot be legalized or excused. It is simply illegal to act on orders that are naturally wrong.
So having asked the German state attorney I know, he has confirmed my hunch. If Trump were to say this in Germany, that would constitute "Volksverhetzung" literally incitement of the people according to § 130 StGB (German penal code) which is punishible from a fine to 3 years in prison. And to add, it's pretty clear cut.
Since he's a foreign dignitary (fuck it feels wrong to call him that), he has diplomatic immunity though
