Sadly we broke that a long time ago and Humpty Dumpty isn't going back together again.
We grow most of their food, and make most of their technology. What are they contributing besides hate and divisiveness?
I've been thinking along those lines myself lately - like India and Pakistan partitioning in 1947.
It's not only depressing but it's a tragedy for the country especially at a time when China is on the ascendancy, Russia is becoming more Stalinist like and the world generally is becoming a more dangerous place.
The lack of a common narrative within the US is potentially devastating not only for the US itself but also other Western democracies. This division within the US ought to be of primary concern to US citizens but it doesn't seem so.
I'm not in the US and I can't help feeling that the decline of the US and its world influence is of more concern to people like me than it is for many US citizens.
As I said it's very depressing and many of us on the outside are looking on helplessly knowing that we can do nothing about it.
