I just point out the US does it, too. All governments, actually. It would be more surprising if there was a government anywhere on the planet who wasn't spying on another country and sending propaganda. It's just how international politics works. Even Canada spies on the US and sends pro-Canadian propaganda our way. And we do it right back to them.

The only way any of it is effective is if there's already people in the target country willing to accept the propaganda. If people weren't receptive to it, the country doing the attack would switch to some other tactic, like sabotage or theft.

Liberals who pearlclutch over Russia should be more concerned about why there are these black holes in politics. Like why can a foreign country buy campaign ads in the US in the first place? Then you can steer things towards Citizens United or copaganda.
