From their twin inceptions, PEACE and ATLANTIS were pitched against each other. First, in the Ibero-American War, PEACEKeepers from Portugal flooded into Mexico to prevent a Spain-funded invasion of the Latin American country. Immediately afterwards, Romania declared war on Hungary which sparked World War I after nations from both alliances threw their weight into the battle. In Western Europe, ATLANTIS troops attempted unsuccessfully to invade France in Operation French Toast. Later, Romania began to beat back Indonesia, pushing them out of parts of China, Pakistan, and India until, in the closing days of the Great War, PEACEKeepers from Indonesia, Hungary, and all other PEACE nations turned the tables on ATLANTIS and drove Romania out of Asia and eventually back to her original borders. After the war, PEACE and other groups returned sovereignty to nations that had formerly been dissolved into the Romanian and Norweigan Empires, including Russia, Ukraine, and Moldova. These cataclysmic events sparked the dissolution of ATLANTIS, which was only solidified when, days later, Sweden declared war on fellow ATLANTIS member Germany.
