I agree that one should expect (some) geographical containment(s) to represent general partonomy; I guess geonames doesn't because there is no canonical property for partonomy. E.g., Geonames has: :parentFeature a owl:ObjectProperty, owl:TransitiveProperty; rdfs:comment "A feature parent of the current one, in either administrative or physical subdivision."@en; rdfs:domain :Feature; rdfs:label "parent feature"@en; rdfs:range :Feature . :parentADM1 a owl:ObjectProperty; rdfs:domain :Feature; rdfs:label "level 1 administrative parent"@en; rdfs:range [ a owl:Restriction; owl:hasValue <#A.ADM1>; owl:onProperty :featureCode ]; rdfs:subPropertyOf :parentFeature . But no :parentFeature rdfs:subPropertyOf http://www.w3.org/2001/sw/BestPractices/OEP/SimplePartWhole/part.owl#partOf. Or :parentFeature rdfs:subPropertyOf dcterms:hasPart. To be honest though, I don't like your example as being a citizen of a country /doesn't/ imply a partonomy relationship to me (neither might some kinds of geographic containment - I'm thinking Lesotho-South Africa).
