I have never been able to understand how countries can claim another as theirs even though they are separated by hundreds of miles by water. This might have been the norm in the 1700/1800's but its crazy to apply it now. Britain has ruled over Australia,America,South Africa, Ireland,Bermuda,Figi,Canada and New Zealand to name a few, only 80 years ago we controlled a quarter of the worlds population, 500 million at that time, if we were controlled by a small far away country I am sure we would all have different things to say and not a lot of people would accept it.
Money/Oil etc will always win in the end.
