In fact, I think Billy Bragg's version of the Internationale sums up my position on the matter:
"Let no one build walls to divide us,
Walls of hatred nor walls of stone.
Come greet the dawn and stand beside us,
We'll live together or we'll die alone.
In our world poisoned by exploitation,
Those who have taken, now they must give!
And end the vanity of nations,
We've but one Earth on which to live.
So come brothers and sisters,
For the struggle carries on.
The Internationale,
Unites the world in song.
So comrades, come rally,
For this is the time and place!
The Internationale,
Unites the human race.
