It isn't anywhere near the worst thing the UK has done (in this case for the US so, I think they share a bit of the blame). The key issue here is that it is ongoing - the UK still isn't allowing them back or properly compensating them. The UK government should recognise that what it did was wrong, establish that the land belongs to the Chagossians and, broker an agreement where the US tries to try to buy the land needed for the base from them. There will be a price that the US government is willing to pay to keep the base there, that the Chagossians will accept, I suspect. If there is not, the base should have to be moved over a period of five years. An alternative might be the construction of an artificial island nearby. It is also possible that the value to the Chagossians, and the cost of building an artificial island, are both greater than the value to the US of having the base, in which case they should just abandon it. This is the only fair solution IMHO.
