Hi,You can fix the query by replacing the following SPARQL statement: ?country wdt:P31 wd:Q6256. ...with the following 2 statements: ?country p:P31 ?countryStatement. ?countryStatement ps:P31 wd:Q6256.
Pro tip: you can also write ?country p:P31/ps:P31 wd:Q6256.so the query looks almost as simple as before. Replacing wdt:Pxxx with p:Pxxx/ps:Pxxx is a general pattern to switch from "preferred" statements to "all" statements.
This will include deprecated statements though. To filter those, one would need the longer version and write something like
?country p:P31 ?statement .
?statement ps:P31 wd:Q6256 .
FILTER NOT EXISTS {?statement wikibase:rank wikibase:DeprecatedRank}
