Question

how was europe doing 3 years into ww1 and why did america joining the conflict make such a big difference? your answer

Explanation:

Three years into WWI (by 1917), Europe was exhausted. Both Allied (e.g., France, UK) and Central Powers (e.g., Germany, Austria - Hungary) faced massive casualties, economic strain (rationing, debt), and war - weariness. America’s entry mattered because it provided fresh troops (relieving Allied manpower shortages), vast industrial resources (weapons, supplies) to sustain the Allied war effort, and psychological momentum, tipping the balance against the exhausted Central Powers.
