KADIZ

There are numerous maps that prove Dokdo as part of Korean territory.

Among them, this map is very convincing(in my opinion) .

It shows that UN Forces included Dokdo in KADIZ(Korean Air Defense Identification Zone).

In 1950, during the Korean war, the UN established an air defense zone in order to defend Korea. Dokdo is included in KADIZ and they are still using this standard today.

This clearly proves that UN is protecting Korea as well as Dokdo, which they regard it as part of Korean territory.

Another proof that indicates Dokdo's sovereignty.
