Who were allies of the US in World War 1?

Germany's biggest rivals/enemies were the Triple Entente, and in particular Britain and France, because they were more stable and had more military power than Russia, who were the other main force in the Triple Entente.

• Britain, in 1914, were the richest nation in the world and had the largest navy with a mass of ships and submarines.
• France had a large army and were technologically advanced.
• The Russian Tsar was not such a skilled leader as his British and French counterparts, so the nation broke down in its unity.
