Well, Asuming they somehow defeated America, I'm a Jew, so I'm so fucking fucked it isn't funny, unless the family up and moved to Manchuko or somewhere else controlled by the Japanese.
We've got some valuable skill sets, and my mother works in finance (well, database administration, call center forecasting, and stuff like that with HSBC, not sure what the equivalent would've been back then,) so that'd be fairly easily done, especially if she could just transfer to a different branch, like the Home office or Taipei.
Maybe I could start a delicatessen, or a hole in the wall diner in the area? I don't have any other real skill sets aside from cooking, and a little taste of home for the American expatriate community where ever we landed would be something nice.
