The Wikipedia entry is unverified research, is it?
References from High Court Judgements, the International Court of Justice, Constitutional Law, the BIOT treaty, numerous press articles from across the globe and political spectrum. 84 references altogether and five books on the subject, all of which you are are at liberty to read …. and yet you claim the page is unverified.
I linked to the Guardian piece because it gives a clear summary and is not behind a paywall.
You asked for “Explanation please”. What is it that you want?
