When writing about the Nazi regime or the ideologies associated with it, it's important to use grammatically correct and appropriate forms. Here's a breakdown of the different forms:

1. "Nazis" is the plural form of the noun "Nazi" and refers to multiple members of the Nazi party or the Nazi regime as a whole. For example, "Many Nazis were tried for war crimes after World War II."

2. "Nazi" is the singular form of the noun, referring to a single member of the Nazi party or the ideology itself. For example, "He was a Nazi sympathizer."

3. "Nazis'" is the plural possessive form, used to indicate ownership or association of something belonging to multiple Nazis. For example, "The Nazis' uniforms were distinctive."

4. "Nazi's" is the singular possessive form, used to indicate ownership or association of something belonging to a single Nazi. For example, "The Nazi's rhetoric was filled with hate."

To determine which form to use, consider the grammatical rules for plurals and possessives. Use "Nazis" and "Nazi" when referring to multiple or singular members of the Nazi party, respectively. Use "Nazis'" or "Nazi's" when expressing ownership or association.
