On the first day of invasion, there were about 14000 arrests in Moscow of anti Pootin and anti war activists.
It seems to me that not all is ok within Russia. If there were 14000 arrests, then there are literally millions of Russians against Pootin and against the Ukraine War, mostly younger Russians.
Now, even with the media black out, Russians still have access to western media, facebook, twitter and other social media outlets like Instagram through VPNs. It's usually the younger and more tech savvy that would go to this trouble. so many Russians are indeed well inform, despite all the challenges they face. And many are against Pootin. Some are brave enough to sopeak out and get arrested. Most are not as they may hold jobs in the public sector or in an area where they can be affected.
In my view, Russia is on a knife edge. It may see civil disobedience on a scale never seen before. Especially if these sanctions take hold and effect the people.
