Should the English language return to referring to countries with the pronouns she and her instead of 'it', for the explicit purpose of discouraging fighting between countries?

Yes
No, fighting is fine
No, sexist reasoning
No, assumes gender

Many English style guides discourage the use of she for countries or inanimate objects; such use may be considered dated or sexist.

"She" is used for ships in formal documents such as Royal Navy news headlines, official US Navy documents, ADF news, and Forbes.
