WW1 Country

You don't attack the British and instead, you moderate your U-Boat Campaign. Then you win the Second Battle of Ypres by firing gas at the British. Then Romania joins the war on the opposite side but we occupy them. Then, there's a naval battle between you and Britain, then, somehow, even though your navy is weaker, you win the battle. Then, you make an air raid on London. Then you attack the French in Verdun. A lot of soldiers die. Then, there's the battle of Somme that's 5 months long and you lose 500,000 troops. In the end, we gain 25 miles of land. Then the United States declares war on us. Then you force the Russians to sign a harsh treaty and give you $300,000,000, but you don't have to make them sign. Should we make them sign it?
