World War One Decision Tree Allied Powers

Scenario: Your country is in an alliance with Britain, France and
Russia Russia is an ally of Serbia. Your alliance is at odds with the Central
Powers (Germany, Austria-Hungary, and the Ottoman Empire).
You are concerned about the Central Powers for several reasons.
Germany has built a huge army and navy and is becoming very aggressive.
Competition in Africa and Asia for resources has raised tensions and sporadic
fighting is breaking out. The rise of aggressive nationalism is fueling border
conflicts between France (your ally) and Germany (also between
Austria-Hungary and Serbia). Tensions in Europe are rising, and countries are
stockpiling weapons and preparing for war.
News flash! The Archduke of Austria-Hungary has been assassinated by a
Serbian nationalist! Austria-Hungary is threatening to declare war on Serbia! If you
cannot defuse the situation, this conflict will kick start the alliance system, and you
will be pulled into a devastating war!

What do you do

The Allies of World War I or Entente Powers were the coalition of countries led by France, Britain, Russia, Italy and Japan against the Central Powers of Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria during the First World War (1914–1918).

By the end of the first decade of the 20th century, the major European powers were divided between the Triple Entente and the Triple Alliance. The Triple Entente was made up of France, Britain, and Russia. The Triple Alliance was originally composed of Germany, Austria–Hungary, and Italy, which remained neutral in 1914. As the war progressed, each coalition added new members. Japan joined the Entente in 1914. After proclaiming its neutrality at the beginning of the war, Italy also joined the Entente in 1915. The term "Allies" became more widely used than "Entente", although the Principal Allies of France, Britain, Russia, Italy, and Japan were sometimes known also as Quintuple Entente.[1]

The United States joined in 1917 (the same year in which Russia withdrew from the conflict) as an "associated power" rather than an official ally. Other "associated members" included Serbia, Belgium, Montenegro, Asir, Nejd and Hasa, Portugal, Romania, Hejaz, Panama, Cuba, Greece, China, Siam, Brazil, Armenia, Guatemala, Nicaragua, Costa Rica, Haiti, and Honduras.[2] The treaties signed at the Paris Peace Conference, 1919 recognized the United Kingdom, France, Italy, Japan and the United States as the 'principal Allied powers'.
