How and why did the usa get involved in wwi

Hey there, the United States of America got involved because The World War erupted in the year 1914, when the President Woodrow Wilson pledged in the US. An many ships from the US were traveling to Britain and got hit  damaged and sink  by the German mines.

Hope this helped

no options provided, here,but the answer to this question is often: a historian cites a japanese newspaper article published a year after the end of world war ii in order to draw conclusions about the effect of the war on the japanese economy.

clearly from the answer, the historian alludes to historical sources,and records to aid in analyzing and drawing conclusion on the effect of the war on the economy of japan.
