We don't know for sure. The focus of the story was mainly on Andy and his toys, so his dad's situation wasn't explored. It could be that the filmmakers wanted to keep the attention on the child's imagination and playtime.
The assassination of Franz Ferdinand was a significant event that led to the start of World War I. Archduke Franz Ferdinand of Austria - Hungary was assassinated on June 28, 1914, in Sarajevo. A group of Bosnian Serb nationalists, who wanted Bosnia to be free from Austro - Hungarian rule, planned the attack. Gavrilo Princip, a member of the group, shot and killed Franz Ferdinand and his wife Sophie. This event set off a chain of diplomatic and military escalations among the European powers that ultimately led to the outbreak of the Great War.
The challenges were numerous. Socially, Sophie's status was not on par with what was expected for someone marrying an Archduke. This led to resistance from the court. Politically, there were concerns about how their union would be perceived within the empire and among other European powers. There were also cultural aspects, as the court's traditions were deeply ingrained and didn't easily accommodate their relationship.
It depends on your perspective. Some parts of the story might be based on real events or inspirations, but it's likely a fictional creation with elements of imagination.
