As you say heric, the stuff in that report seems pretty questionable.
Agents are prone to massage the truth in their reports, so even if the papers are genuine it doesn't mean they are true.

However the underlying assumption seems fair enough. The fact is, the antagonism between the USSR and the USA wasn't primarily to do with the economic setup in the USSR. Although this has changed somewhat, and so have other things, so that it's "Russia" these days, this doesn't mean the antagonism has gone. In fact with US forces settled in throughout lkarge parts of the old Sovet Union, and with NATO now up to the Russian borders, there is in some ways more reason for antagonism than there was in the old days.
