David, I am simply somebody who suspects the US could set a better example; and that it has within its gift, the ability to do so rather than continuing to act as the monster it has become.
When a nation can say 'we recognise that your nation behaves the way it does partly because of our own nation's previous actions.. but we want to put that right and atone for it.' - it will be a huge step forward. But the US doesn't want to do that, it wants to play 'King of the heap'.
