Although the United States declared war on Germany on April 6, 1917, it did not initially declare war on the other Central Powers, a state of affairs that Woodrow Wilson described as an "embarrassing obstacle '' in his State of the Union speech. Congress declared war on the Austro - Hungarian Empire on December 7, 1917, but never made declarations of war against the other Central Powers, Bulgaria, the Ottoman Empire or the various co-belligerents allied with the Central Powers. Thus, the United States remained uninvolved in the military campaigns in central and eastern Europe, the Middle East, the Caucasus, North Africa, Sub-Saharan Africa, Asia and the Pacific.
