Ascension Island is a small island 5000 miles away in the South Atlantic. Used as a staging post during the Falkland conflict.
To be fair - it' definitely a place where people would be safe from persecution due to their race, religion, nationality, political opinion, gender identity or sexual orientation.
And it's not like other countries do something similar....
I also suspect that it would appeal to many people - a way to discourage people trying to enter this country by sending them 1000s of miles away to a small Atlantic island.
