The Southern Kuriles are officially claimed, but what I was referring to was all of the Kurile Islands. That's why I didn't use the word "southern" in my original post. 

 As for a new article, I would suggest being cautious as I foresee the unofficial list being filled up quite quickly with a lot of fringe / unsubstantiated claims. So it would be better to leave the current pages as is, and start a new List of unofficial territorial disputes.
