Final answer:
The question about why Adolph begins striking Sambo cannot be answered accurately as the provided excerpts do not contain any character named Adolph striking another named Sambo; the texts provided are unrelated and from different contexts.
Step-by-step explanation:
The query as to why Adolph begins striking Sambo appears to be rooted in a misreading or conflation of different textual materials. None of the provided excerpts depict a character named Adolph striking another character called Sambo.
Instead, these excerpts relate to various unrelated histories and literary contexts. For example, one excerpt discusses Adolph Hitler's declaration of war against the United States, a historical WWII event.
Another references internal changes in boxing champion Muhammad Ali's approach to psychological warfare against his opponents. Additionally, the mention of Stalin alludes to a historical perspective on the Soviet Union's stance during WWII.
Lastly, the excerpt with characters named Sarah, Sammy, and Adoniram is likely from a piece of literature unrelated to the subject of the question. Consequently, without the correct context or a clear association with the characters named Adolph and Sambo, providing factual assistance on the query is implausible.
