The document discusses the key issues and leaders at the Paris Peace Conference in 1919 following World War I. The "Big Four" leaders - Lloyd George, Orlando, Clemenceau, and Wilson - had to address reparations, restrictions on Germany to prevent future wars, redrawing borders to satisfy ethnic groups like the Poles and Serbs, and how to resolve international conflicts and prevent future alliances that could lead to war. Advisors to the delegates were tasked with prioritizing their nation's priorities on these issues and determining what they would be willing to compromise to achieve security and prosperity goals.
