A Merry Christmas to ISIL (chalked on a Paveway)
Surprised not much mention of WWII so far. In those days they paid us by the day, seven days a week, so you fought the war seven days a week. Christmas, Easter and all the other Bank Holidays included.
The 1914 Football Match was a one-off: there were no more after that.
In my neck of the woods, the Jap was quite happy to kill you on Christmas (or any other ) day. So you had to return the compliment.
War is War. The normal rules don't apply.
