War Plan Red - The U.S had plans to invade Canada, UK & Australia
Lucky we had that second World War, because the U.S were getting real antsy, just sitting there. So twitchy, in fact, they drew up serious plans in the '20s to invade Great Britain, starting with a strategic division of Canada. Australia plays a role too. WTF, America, WTF.
http://en.wikipedia.org/wiki/War_Plan_RedThe plans (declassified in the '70s) refer to countries as colours (y'know, so as not to give anything away) Canada, is "crimson", the UK is "red", India is "ruby", Australia "scarlet", New Zealand "garnet", and Ireland "emerald" according to War Plan Red.
