If you are talking about Teddy Roosevelt, well he died 20 years earlier in 1919.
If you are talking about Franklin Roosevelt, he like all Presidents hated war. When Hitler attacked Poland in September 1939, Roosevelt stated that, although the nation was neutral, he did not expect America to remain inactive in the face of Nazi aggression. Accordingly, he tried to make American aid available to Britain, France, and China and to obtain an amendment of the Neutrality Acts which rendered such assistance difficult. He also took measures to build up the armed forces in the face of isolationist opposition.
With the fall of France in 1940, the American mood and Roosevelt's policy changed dramatically. Congress enacted a draft for military service and Roosevelt signed a "lend-lease" bill in March 1941 to enable the nation to furnish aid to nations at war with Germany and Italy. America, though a neutral in the war and still at peace, was becoming the "arsenal of democracy", as its factories began producing as they had in the years before the Depression.
The Japanese surprise attack on Pearl Harbor, December 7, 1941, followed four days later by Germany's and Italy's declarations of war against the United States, brought the nation irrevocably into the war. Roosevelt exercised his powers as Commander-in-Chief of the Armed Forces, a role he actively carried out. He worked with and through his military advisers, overriding them when necessary, and took an active role in choosing the principal field commanders and in making decisions regarding wartime strategy.
He gave priority to the western European front and had General George Marshall, Chief of Staff, plan a holding operation in the Pacific and organize an expeditionary force for an invasion of Europe. The United States and its allies invaded North Africa in November 1942 and Sicily and Italy in 1943. The D-Day landings on the Normandy beaches in France, June 6, 1944, were followed by the allied invasion of Germany six months later. By April 1945 victory in Europe was certain.He gave priority to the western European front and had General George Marshall, Chief of Staff, plan a holding operation in the Pacific and organize an expeditionary force for an invasion of Europe.

Hitler's aggressive expansionist policies, militarization, and pursuit of Lebensraum were key factors in leading to the outbreak of war in 1939.
