> People before WW1 thought war was impossible thanks to how the economy was so interconnected That is not why everybody thought war was impossible. The reason they thought war was impossible was the King of England, the Kaiser of Germany, and the Tsar of Russia, i.e. the major belligerents in WWI, were all cousins. They were Queen Victoria's grandchildren. Those weren't the only grandchildren on the throne who ended up taking up arms and entering the war. Given how a total of seven of the belligerents were related, including the 3 largest belligerents, nobody thought the family would go to war with one another. They thought wrong.
