My interpretation of a World Court precedent or yours is original research and doesnt have any weight here  If you can find an authoritative source that applies the precedent of Denmark vs Norway to these Arctic islands and draws some conclusions thats great  From my admittedly quick examination the decision does not match your characterization of it  But thats neither here nor there because neither of us is qualified to judge the quality of legal arguments  If the claims to Wrangel Island etc were made by the authority of Congress and recognized by the US government I have no problem with the articles saying so with good documentation of course
