imagine your entire massive nation got absolutely dominated and subjagated for over a century by a tiny island thousands of miles away with a fraction of your population and resources, where you outnumbered the conquerors a million to one and it would have taken them months to get a message back home let alone for any help or reinforcements to be mustered and sent over. imagine having such a ridiculous advantage over the invader and still getting so utterly dominated to the point where even close to a century after they left (and left just of their own accord, not by any means of violently forcing them out) you are still stereotyped as soft weak yes men. you'd probably have some kind of inferiority complex and revenge fantasies too.
