It’s a survey about what people in some countries in the eu want. Lots of stuff. Not a single question explicitly about Greenland. But evidence that can lead to more informed opinions (eg countries who wouldn’t mind sending troops to Ukraine now which isn’t an eu country).
I know it’s a lot of work making inferences from data where you can’t just ctrl f a word and get an answer.
But the overall picture isn’t that citizens of the eu are feeling passive and just going to write letters. And I know that wasn’t a question either. Tricky is this thing called evidence.
And this was just one survey of many that exist.
