Ambassador Grenell flaunted diplomatic protocol by making a series of statements that appeared to undermine the current German government, support right-wing political parties, and criticize the “blatant anti-Americanism” in German media.1 Former German ambassador to the United States, Wolfgang Ischinger, retorted via Twitter: “Never tell the host country what to do, if you want to stay out of trouble.” Trump’s presidency has only made these changes more apparent. ...teaching US foreign policy now in Germany demands engaging in difficult discussions about the future of German foreign policy. The discussions include the controversial issue of increasing German defense spending and its willingness to use force; thinking critically about NATO and the European Union’s dependence on the US security umbrella; and reconsidering the leadership role that Germany could and should play in managing international order on topics ranging from the rise of China to nuclear nonproliferation and climate change.
