Pasta Sentient said Casus Belli
The standard has already been set that Britain does not require so petty a thing as a "Casus Belli" before going to war. The British Empire does not need a reason for war, after all, but a reason for peace. Let us not forget the blockade of the North Atlantic. Victoria may be gone, but the mind behind her insanity (Pasta's mind), is still very much active.
