Hello, I started reading the volumes from 1977, while it’s interesting to read since there’s a bunch of testimonies and it’s kind of a window through time since by now, Aron work would have dated stuff in it, his work on vichy did seemed to have the shield and the sword theory (it was done in 1954 and it was seemingly already criticized in the 50’). Old works on the war can be interesting to read but be aware there can be wrong theories/innacuracies and dated stuff because authors of the time didn’t access to as much archive as we do now.
