Massive casualties pick Cause or effect of America’s entry into WWI ?

Effect: Massive casualties.

America's entry into World War I had a significant effect on the number of casualties in the war. Prior to the United States joining the conflict in 1917, the war had been ongoing for several years and had already resulted in high casualties for the countries involved. However, with the addition of America's military power and resources, the scale of the war escalated, leading to a significant increase in casualties.

As the war progressed, the entrance of the American forces provided a boost to the Allies, specifically in terms of manpower, weaponry, and supplies. This increased firepower and support allowed the Allies to launch major offensives against the Central Powers, resulting in more intense and deadly battles. Notably, the American Expeditionary Forces (AEF) participated in crucial battles such as the Meuse-Argonne Offensive, which was the largest and deadliest campaign of the war, resulting in over 26,000 American casualties.

Moreover, the scale of casualties was also exacerbated by the use of new and devastating weapons during the war. Technological advancements, such as machine guns, artillery, poison gas, and trench warfare tactics, had already proven to be deadly. With America's entry, the war became even more lethal as these weapons were utilized on a larger scale.

Overall, while America's entry into World War I was a crucial turning point in the conflict, it also contributed to the massive casualties seen during the later stages of the war due to the increased intensity and scale of the fighting.
