To quote a previous post of mine:
With regard to the Sealand Recognition Bill, I would have to state my unequivocal opposition.
"Sealand" is actually not an island or a territory, but merely a man-made structure: a partially sunken Royal Navy barge in the North Sea. The structure was built by the British government, and lies within the limit of British waters; thus, by any reasonable interpretation of international law, it is the property of the United Kingdom (albeit abandoned).
As I said earlier, I don't think that it is necessary to recognize a sunken ship with a population of five as a sovereign nation (Governor MAS's objections notwithstanding). So, I would request Sen. King to withdraw the proposal.
