It’s obviously would be an insane idea to try and destabilize Russia, but it was an equally insane idea to try to goad Russia into a war and continue escalating to the point where we are at now. Once the war started, the explicit stated goal from the west was to try and destabilize Russia economically to cause regime change. This is still the hope a lot of people in the west cling on to. Most people don’t seem to be asking the question of who would take power if regime change actually happened. It’s pretty clear that somebody like Medvedev or Kadirov would end up in charge, and Putin is a moderate compared to these people. It’s pretty clear that the west is not acting in a rational way here.
The one thing we’ve learned from the whole wagner fiasco is that conditions for any sort of a coup simply don’t exist in Russia. All of the military and politicians quickly lined up behind the government. If anything, I’m sure that this created an opportunity to purge people who might’ve been sympathetic to a coup.
