For the first 3 days there were two sides. Now it's the whole world fed up with Putin and his cronies. I see no way for him to walk this back. Russia can't deliver its promises, like wheat to China, if it is completely cut off from imports (parts). And for exports, can't get ships to carry it. I just can't see how he's not done in the weeks ahead.
We have to keep in mind everyone, even the Russians, are in shock. It'll take a little time. Each day his speeches become nuttier than the day before.
