Oy. What is this diplomatic spat about this time? Neither of your nations have had slavery for over 120 years, you both share a language and you both cherish your independence, so why do you keep fighting like this?
You've only just repaid the reconstruction loans that were offered as part of the Marchelle Plan following your 1933-38 war, and now you're going to have to ask the Alliance of the Four Empires to pay your way again if you start firing at each other now!
So Yankees, keep your capital in Washington, because as far as this Londoner can see, the only thing stopping your politicians from dragging you into another pointless war is the fact that they fear that they themselves may get shelled as soon as it starts. So no, stay where you are and just learn to co-exist damn it.
