1) It is well reported that, long since, GPS was not jammed per se, but overrode with false data wherever Putin's motorcade was travelling. One ship in the Black Sea reported errors - it is serious because ships take a long time to slow down, and it was Putin's convoy in the area. GPS signals are weak, falsifying them only needs a stronger signal.

2) The ex PM of Finland gave a very measured interview on Youtube (can't remember the URL). He made the point that there are 3 words for "truth" in Russian, one of which is Pravda. He gave the translation of "tactical truth". In English that might be "white lie" - there you have it, Russian language/culture use alt truth, where English says lie. Its all in the emphasis. And wasn't/is Pravda a Russian newspaper?
