The explanation is that the second and third generations of people who were relocated there were born up there. They don't know any other place. To them, this is home, as George has said many times now. They have no other place to go, because they were born up there, and it's the only thing they know.
I think that the attitude of people living in those two communities is very positive. They feel that they contribute to the sovereignty of this country, and they're proud of that. We consider ourselves guardians of the High Arctic because our ancestors are buried there, and our descendants are continuing to live in those communities and are helping the country assert its sovereignty in the Northwest Passage.
To answer your question, I think the people living in those communities are prepared to live up there for the rest of their lives, and they feel that their contribution is important.
