Hannibal Barca, known for attacking Roman forces during the Second Punic War, likely did not attack groups not involved in the conflict, such as Germanic tribes or Egyptians, although the question does not specify which groups are being considered.
The question refers to the actions of Hannibal Barca, a famed Carthaginian general during the Second Punic War. Hannibal is renowned for his military campaign against the Roman Republic, particularly his bold crossing of the Alps and his series of victories on Italian soil. However, there seems to be a confusion regarding a group he did not attack since the question does not specify which groups are being considered.
By most historical accounts, Hannibal focused his attacks on Roman forces and their allies, so we could infer that he did not attack civilizations that were not part of the conflict, such as those farther to the east or north of Italy, like the Germanic tribes, or those south across the Mediterranean, such as the Egyptians.
While the War Elephants that survived Hannibal's crossing of the Alps were notoriously effective in battle, there is no specific record stating a particular group that Hannibal deliberately avoided attacking unlike the Romans.
