Step-by-step explanation:
President and the Washington Naval Conference
The president that dealt with the foreign issue of the Washington Naval Conference of 1921-1922 was President Warren G. Harding. The conference aimed to address the naval arms race following World War I and resulted in the Five-Power Treaty, which was meant to limit naval capacities and arms construction, particularly warships and aircraft carriers. This was an effort to lessen the chances of war and cut defense spending among the nine signatory nations, which included major powers like Great Britain, the United States, and Japan. The treaty established ratios intended to maintain a balance of naval power without further sparking an arms race. These treaties were part of a larger post-WWI movement towards disarmament and international cooperation, a precursor to the peace efforts that would continue into the late 1920s with agreements like the Kellogg-Briand Pact.
