It is nice to have an agreement to do it, but is it moral and ethical to do it?

There would have been no problem if Angela had taken the honest stance of Australia:

Don't bother coming.

WE DON'T WANT YOU HERE!

There is only one Western nation who wants them. It is the USA.
The problem is there one sea, the Mediterranean to cross and an ocean to cross to reach USA.
