Like most above I think the list would be long, but most significantly I would select the following as being top of that list:

1. Stood by us in time of need, when freedom and the democractic system of government was in danger of being usurped.

2. Providing the best example in the world to date of how a multi-ethnic, multi-racial and multi-religious society can not only peacefully co-exist but prosper. I know it is not perfect, few things in life are, but in general they have got more things right than wrong.
