They started hating Russia in 2014 when they were not allowed topple Assad in Syria or conquer all of Ukraine.
Putin is channeling Stalin, and probably knows it.
Never forget that modern-day Russian culture is heavily influenced by the Mongol hordes who over-ran Russia in the 13th century. They never really left.

“They started hating Russia in 2014 when they were not allowed topple Assad in Syria or conquer all of Ukraine.”
Also in 2014, Russia outlawed Grooming of little children, so that, no doubt, angered a bunch of people here.
It was slightly before that.
Russia and China abstained from the Libya “protect civilians” UN vote. Either could have prevented military action there, but the wording of the resolution did not authorize an attack on Ghadaffi or extensive bombing. So they abstained.
The resolution carried. As soon as the sortie total started to accumulate, paying big money for fuel with Libya offline, they translated that resolution into assassinating Ghadaffi and massive bombing everywhere.
Russia and China both told the US there would never again be any resolution in the UN authorizing any collective military action that they would allow to proceed.
That’s why Assad is still in Syria. Russia said no and sent its own forces there.
