"My nation is great" Too vague to be useful measure.

The question "my nation is great" is far too vague to offer any meaningfull insight.

This can be interpreted from either a nationalistic view or a pragmatic view. I could argue that what my country is great compared to a country that doesn't align as well with my view.

Or another interpretation would be that no matter the situation my nation is great which would be a nationalistic take.

A better question if its being used to determine nationalistic view could be "my country is great no matter what it does" for example.
