Final answer:
Colonel Claus von Stauffenberg lost faith in Hitler due to his destructive policies and the atrocities of the Nazi regime, leading him to partake in an assassination attempt in July 1944, which, after failing, resulted in harsh reprisals and the execution of nearly 5,000 people.
Step-by-step explanation:
Colonel Claus von Stauffenberg lost faith in Hitler due to the destructive path Hitler was leading Germany down during World War II. Stauffenberg was deeply opposed to the atrocities committed by the Nazi regime and was alarmed by the Axis powers being in retreat, fearing that Hitler would rather see Germany destroyed than surrender. This led him to participate in the July 20, 1944, assassination attempt against Hitler. Although the bomb placed by Stauffenberg went off, Hitler survived with only injuries. The consequences of this failed plot were severe, resulting in the execution of almost 5,000 individuals associated with the resistance against Hitler.
