Assassination Causes World Destruction

Recent discoveries have shed light on the underlying cause of WWI, the assassination of Archduke Franz Ferdinand and his wife. Next in line for the throne, Mr. Ferdinand went to Bosnia after being invited to see their army march by General Oskar Potiorek, not knowing that six assassins were waiting for him.
After leaving the train, Mr. Ferdinand and his wife got onto a convertible in a motorcade of 6 vehicles to head through town. Passing a garden, the first assassin failed to take action, but the second assassin threw a bomb he had at the cars, but the timing meconizm caused the bomb to blow up the wrong car. Arriving at city hall, the Archduke couldn’t make his speech because it was covered in blood from the bombing. The mayor ended up talking to the crowd, while the small town police force planned how to protect the man from another attempt on his life. After the speech, Archduke Franz decided to go the hospital to visit the people who were injured in the earlier bombing. Princip, the master mind of the whole assassination operation was in a coffee shop when he saw the Archduke’s car turning around. The driver had taken a wrong turn and needed to turn around. Running out of the coffee ship, Princip shot multiple rounds into the car criticly wounding the Archduke and his wife, who died on their way to get medical support. Franz-Ferdinand's last words were "Sophie, Sophie! Don't die! Live for our children!" followed by six or seven utterances of "It is nothing."
Being outraged, Austria-Hungary saw this as their chance to settle a long dispute once and for all and sent a letter to Serbia demanding the stop of propaganda and to arrest the people involved with the assassination giving only 48 hours before further action was taken. After this threat, Austria’s alliance with Germany and Serbia’s alliance with Russia and all of the other secret alliances came to light. While Serbian men were on a boat, Austrian men fired at them to warn them off, but Serbia was not happy and declared war.
