Final answer:
It is false that the Poleis and Athenians showed war and dominance in a good way. The era is noted for cultural and intellectual achievements, and the Peloponnesian War ended Athenian imperial ambitions and disrupted peace until Macedonian conquest.
Step-by-step explanation:
It is false to assert that the Poleis and Athenians were able to show war and dominance in a good way. In ancient Greece, particularly during the Peloponnesian War, the Greeks displayed prowess in war and rhetoric, as signified by the Homeric values which emphasized strength in arms and skill in words. This mindset was a product of their victory against the Persians and the subsequent confidence it instilled in them regarding the superiority of their civilization and its cultural achievements. However, the Peloponnesian War revealed tensions and conflicts among the Greek city-states, notably between Athens and Sparta. While there were truces and periods without active combat, the war led to a reshaping of the Greek political landscape, putting an end to Athens’ imperial ambitions and the classical period. Peace in the region was only achieved with Macedonia's conquest. Historically, the era is celebrated for its intellectual and cultural contributions rather than the glorification of war and dominance.
