Definitely grateful for the sacrifices that have been made in the past, but I'm looking at things based on how the world is set up today. It has become a much smaller place -- people and capital can move around more easily.
I've personally never had a very strong national identity (others do seem to have that), and I think in part it's because it has become so easy to move around.
And if you travel a bit, you realise people are actually not all that different. A lot of them have similar priorities: build out a good life, raise children, care for their friends and loved ones, have fun, etc.
