Overall, the Nazis dealt with opposition mostly through force and oppression, discouraging any forms of rebellion within the country and punishing anyone who did go against them brutally through torture and murder. Due to this, not many successful forms of opposition were present during this time which gave Hitler peace of mind and let him focus on other areas of his dictatorship. However, there were a few plots including Elser's bomb plot and Operation Valkyrie which almost did succeed that worried Hitler and he then began tightening his grip on society. With Operation Valkyrie being so late into WW2, and it coming from members of his own army that he thought he could trust, Hitler realised then that no one could truly be trusted within his own party; even though he had many people executed in response to Valkyrie, he couldn't be sure that everyone he was working with was on the same side as him. Due to this, he became increasingly paranoid and harsh towards everyone within the Nazi Party and Germany as a whole.
