With the Discovery of trench warfare, There was a need for weapons that were capable of long-range destruction and also inflict maximum damage at the same time. this resulted in the invention of many new weapons.
Outlays for troop training, weapons, and munitions increased fifteen-fold from 1916 to 1918. In addition, the Treasury lent generously to US allies. Spending quickly outpaced tax revenues, and the Treasury mounted a series of war bond or “liberty loan” drives to raise additional funds.
Their entry into the war boosted the morale of the other allied nations. Morale completely depleted seems how the war was ultimately a stalemate and lives were being lost needlessly. American entry into the war also discouraged the Axis powers, and later after America's entry the Axis powers began to drop deeper into fear. America was the turning point for the war. The Axis powers were winning and if it weren't for America, then the Axis powers would have prevailed and the world would not be the way it is today. (This is what I think about it, it might not be entirely correct.)
