What is the smallest country in the world?

According to the 1982 United Nations Convention on the Law of the Sea, there is no transitional law and no possibility to consent to the existence of a construction which was previously approved or built by a neighbouring state. This means that artificial islands may no longer be constructed and then claimed as sovereign states, or as state territories, for the purposes of extension of an exclusive economic zone or of territorial waters. However, since Roughs Tower is not an artificial island but a sunken ship, it would be necessary for Her Majesty's Crown Estate (which owns the land itself under the tower) to act as the complainant landlord in order to get the wreck removed from its property. If Sealand is a sunken ship rather than an artificial island then no claim to statehood can be made, as a ship cannot constitute the "permanent" territory required for statehood to be established. What is more, military ships and aircraft are the property of the State that commissioned them.
