This one might work, too (from Wiki):

One of Wilhelm's diplomatic blunders sparked the Moroccan Crisis of 1905, when he made a spectacular visit to Tangier, in Morocco. His presence was seen as an assertion of German interests in Morocco, in opposition to those of France. In his speech, he even made remarks in favour of Moroccan independence, and this led to friction with France, which had expanding colonial interests in Morocco, and to the Algeciras Conference, which served largely to further isolate Germany in Europe.

Moreover, the poor impression left by the German troops’ late arrival was made worse by the Kaiser’s ill-conceived farewell address (depicted here), in which he commanded them, in the spirit of the Huns, to be merciless in battle. Kaiser Wilhelm II’s public relations blunders, particularly in the field of international relations, were legendary. He was known for bombastic cant and grandstanding – although his words were often more threatening and aggressive than his actions.
Come one, there is so much Trump in there.

Granted, Wihlelm II. uses more complicated words, but you have to consider that 100 years have passed since then and Twitter hadn't been invented yet.
