Echoes of assassination of the archduke that led to WW1.

No one in Austria-Hungary’s government was particularly upset by Franz Ferdinand’s death; indeed, they were more relieved he was not going to cause any more constitutional problems. Across the capitals of Europe, few other people were overly upset, except the Kaiser in Germany, who had tried to cultivate Franz Ferdinand as a friend and ally. As such, the assassination didn’t seem to be a major, world-changing event. But Austria-Hungary had been looking for an excuse to attack Serbia, and this provided them with the cause they needed. Their actions would soon trigger World War I, leading to years of bloody slaughter on a largely static Western Front, and repeated failures by the Austrian army on the Eastern and Italian Fronts. At the end of the war the Austro-Hungarian Empire had collapsed, and Serbia found itself the core of a new Kingdom of the ​Serbs, Croats and Slovenes.

I think they did it purely for the symbolism to another "Abe" assassinated back in 1865.

The death of that Abe was a warning to their opponents and allowed them to control the text of the 14th Amendment, which has ushered in much of the confusion we are trying to sort out today.

Blowing up their guidestones was every bit as provocative as the Emancipation Proclamation and the movement to grant liberty to all free from their control. This was a warning in kind to those who remember history.

Meanwhile, in other news, The G. Soros NGO office in Tokyo is holding a Shinzo Abe lookalike competition. The winner will be offered a long-term contract.
