There hasn’t been a bomb like that in Berlin, since May 1945.
The Europeans (read Germans) saw a fool standing before them naked while trying to give himself significance. They know we have a cartoon running the regime. Possibly, they were at first amused by the fool, then the reality of the danger such a fool represents as he is also cic of the most powerful military machine on earth, albeit the fool is trying to transform/change that, too.
