What was a method used by the Nazis to suppress opposition through force?

The method used by the Nazis to suppress opposition through force was the establishment of concentration camps for critics. These camps were used to detain political prisoners, including opponents of the Nazi regime, such as Communists, Socialists, and other dissenting voices. The conditions in these camps were harsh and often lethal, serving as a tool of terror to silence those who opposed Nazi ideology. By imprisoning individuals who could potentially rally opposition or incite rebellion, the Nazis effectively eliminated threats to their power and consolidated their control over German society.

In contrast, public debates would not contribute to suppression; instead, they would allow for the expression of differing opinions. Political rallies, although propagandistic in nature, were typically used to promote Nazi ideology rather than oppress dissent. International public trials might involve legal proceedings aimed at bringing justice or accountability rather than employing force to quiet opposition domestically. Hence, concentration camps represent the most direct and brutal method used by the Nazis to maintain their regime through coercive measures.
