specific terms do vary by jurisdiction.

This is very important. In many jurisdictions things are not that clear cut. In many cases it is up to a rather subjective assessment. Threats alone might justify physical self-defence but the severity or credibility of the threats can influence that. Your options for self-defence can also enter into the assessment. Not all places have "castle doctrine" or "stay your ground" principles and will not allow you to do physical self-defence if you have the option of running away.

Stay safe out there. From the Nazis and from their friends in uniform.
