I think there won´t be anything comparable in America. The special hate an ideological civil war create, let nothing good expect for the treatment of POW´s, at least nothing you write later a sitcom about.
In Europe it depends how the WK goes and how POW`s are treated. Let say there is a german sitcom in the sixties. Here I have the idea, that in the UOB camps were propably guarded by female militias. The joke could be, that there are "romantic collaboartion" between the german POW´s and their female british guards.
