Oh, but the memos are so dull. So boring.
And its exactly the kind of 'you're such a cleaver little boy' solution that they had always been loved for coming up with. How perfect, sink the USSR into a quagmire.
Certainly - well back when people in the White House had scholars on the staff - people knew that the British (and if the British couldn't win a colonial war, no one could) got tied down in those mountains for years, and never made any progress. So perfect if we could somehow get the USSR in that mess.
What of course happened was that we planed the seeds of our own much worse problem later, because clever solutions almost always mess up in the end.
