Like Stead, he believed that the United States and the British Empire would merge into one nation, telling him "We are heading straight to the Re-United States". Carnegie believed that the combined country's power would maintain world peace and disarmament. The creation of the Carnegie Endowment for International Peace in 1910 was regarded as a milestone on the road to the ultimate goal of abolition of war. Beyond a gift of $10 million for peace promotion, Carnegie also encouraged the "scientific" investigation of the various causes of war, and the adoption of judicial methods that should eventually eliminate them. He believed that the Endowment exists to promote information on the nations' rights and responsibilities under existing international law and to encourage other conferences to codify this law.
