With respect,
that the Sovs did things, and therefore knew all about them already, never to my knowledge prevented the RAF and others from highly classifying the information about sov actions, and our reactions... One of those 'but do they know that we know that they know what we think they know?' things, perhaps.
I would presume that talking in general terms about this sort of topic is okay, but a bit of circumspection now and again isn't necessarily going over the top.
