I could ask a number of questions about this, which I just found out about the other day, but the fundamental thing I can't stop musing over is, how do you react to being expected to work with members of a nation (and often, believers of an ideology) that your nation just spent four years mobilizing to destroy? Was there any dissent from within these institutions (in general, but particularly from rank-and-file scientists expected to interface with them on a daily basis)? Was there a range of reactions? Did this evolve? Thanks in advance.
