#DisinfoReview: A return to medieval times?

This week, pro-Kremlin disinformation time-travelled to medieval times, suggesting that the West and/or NATO planned to reduce Russia after the fall of the USSR to the size of the historical Grand Duchy of Moscow. For those who can't quite recall the borders of that Grand Duchy, you can find a map here. Like in any good spy novel, it all supposedly came from secret documents obtained by Russian intelligence services – soon handed over to Sputnik apparently. There was no further information concerning why the West and/or NATO had a plan to divide Russia according to medieval territorial borders, but the curious disinformation was repeated both in Russian and English outlets. Needless to say, the claims were not accompanied with any proof of the existence of such a 'Grand Duchy plan'.
