Uncle Sam weighs the lives lost in the German sinking of the Lusitania (and other ships, as seen on the horizon) to his cash flow from selling weapons and other supplies to the combatants, particularly the allies. The moneybags have tipped the scales. A 1916 postcard by Em. Dupuis.

The neutral United States was angered by Britain's blockade of Germany and declaring of the North Sea as a military zone, but more so by Germany's response claiming the waters around the United Kingdom a war zone subject to submarine warfare. The international outcry following Germany's sinking of Lusitania on May 7, 1915 with 1,100 civilians lost, over 100 of them Americans, led to the campaign's suspension.

Unable to trade with Germany, the US did so with the Entente Allies, providing shells, submarines, and other weapons and the financing for them.

Woodrow Wilson won re-election on the claim 'he kept us out of war,' but continued sinkings, German sabotage, and the Zimmermann Telegram made neutrality increasingly untenable. The US broke relations when Germany resumed a far-reaching campaign on February 1, 1917 in which targeted ships would be given no warning.

Three American ships and fifteen American lives were lost to submarines in March, 1917. On April 6, the US declared war on Germany.

While building its own army of one million men, the United States would not put troops under foreign command. By the end of 1917, fewer than 200,000 American troops were in Europe.

The US agreed to subordinate its troops in early 1918, as Germany struck in five offensives that threatened Allied collapse. Britain and the US agreed to transport American troops on British ships. By July, 250,000 Americans were arriving in Europe each month.

US troops helped stop Germany's drive on Paris at Château Thierry and cleared Belleau Wood. The American First Army attacked at St. Mihiel taking a salient the Germans were abandoning. More difficult was the Franco-American Meuse-Argonne Offensive through well-defended terrain.

United States of America is a country.
