The real meaning of a shared holiday:

WW I was the classic inter-imperialist war, in which working class young men were sent to kill each other for the interests of big business. But on Christmas Day of 1914, the German and British soldiers stopped shooting each other and started singing Christmas carols to each other instead. This led to the soldiers getting out of the trenches, unarmed, and approaching each other, singing as they came. They retrieved their dead comrades who’d been lying there in “no man’s land”, and then they shared chocolates with each other and played football with each other.

Surely, the officers were standing there nervously watching, worrying that real comradeship might break out. Unfortunately, because there was no organization to make the impromptu truce last, the troops returned to their trenches and the next day resumed the mutual slaughter for the interests of capital.

But “Christmas in the trenches” should be remembered every Christmas day.
