The keynote speech was delivered by MacArthur , who had become a hero to Republicans after President Truman relieved him of command in 1951 because of their disagreement about how to prosecute the Korean War , had hopes of obtaining the presidential nomination . In his address , MacArthur condemned the Truman administration for America 's perceived loss of status on the international stage , including criticism of the Yalta Conference and the administration 's handling of the war in Korea . MacArthur also criticized Truman on the domestic front , blaming his administration for wages that failed to keep pace with post-World War II inflation . The speech was not well received , and did nothing to aid MacArthur 's presidential campaign . He curtailed his post-convention speeches and remained out of the public eye until after the election
