1. The US trusted it to be a mostly European war, Woodrow Wilson sought after his tranquility arrangement, and general supposition was against the war. 2. Pivot powers were picking up the high ground, Germany started circuitous assaults on the US, and Germany made an offer to Mexico. 3. They had just given credits and help to the Allied forces, and Germany was antagonistic to the US. The US kept up a noninterventionist position for the greater part of WWI. It was viewed as an European war, battled between European nations over European issues and the American open did not have any desire to go to war for another nation’s motivation. President Woodrow Wilson likewise needed to keep up peace for whatever length of time that conceivable. Notwithstanding, the Axis powers drove by Germany were picking up a high ground in the war and in spite of updates were by implication and specifically assaulting the US. These assaults incorporated a U-vessel’s sinking of the Lusitania, a British watercraft conveying 128 Americans, and the sinking of 7 dealer ships.

The last nail in the pine box was the German Foreign Minister’s message welcoming Mexico to join the war as a partner and promising help in recovering a previous Mexican area (Texas, Arizona and New Mexico). Germany’s antagonistic state of mind towards the US, given the submarine assaults on US vessels and the suggestions to Mexico, combined with the way that the US was obviously and secretly supporting the Allies with weapons, credits and supplies, commanded US passage for the benefit of the Allied forces.
