Why did the US object to Cuba receiving Soviet arms?
A little thing called the "Cold War".... and the fact that the leader of the USSR had said of the west "We will bury you". a few years earlier, was obviously mentally unstable (see shoe-banging incident).
None of that is remotely like 2022 when russia had very lucrative deals with a very (too) supportive Germany and an international order that was all too willing to let Crimea (and maybe the Donbas) to as a fait accompli.... (quite wrongly it appears). He had hooked into the international money train but that wasn't what he wanted...
And of course it had nothing to do with NATO.... cultural insiders (russophones) pro- or anti- putain all dismissed NATO is inconsequential and peripheral pointing out his general rhetoric of russian empire and his desire to 'gather in' the russian peoples (the triune nation).
But russian propagandists are like cheap psychics doing cold readings... they throw out 10 ideas and see which one their mark falls for.
A certain kind of westerner who had come to hate the west and western values jumped on NATO and so they built that up.
Congratulations! You feel for the oldest trick in the book!!!!!
