The best hope for this lies in this country, or southern Spain or Monaco. The oligarch billionaires that live in Mayfair or Knightsbridge, or Puerto Banus or the French Riviera are probably losing a million quid a day each with all this and the sanctions. How long will they wear that? An uprising from within once they get hit in the pocket is the best hope and the most realistic. Putin has lost it clearly. Money men won't have and they won't have it for long. Pres Biden knows this and that is why he spent two weeks telling the world this was happening imminently. He was mobilising the opposition. Boris Johnson has some clout here given the oppo live in London. They are waiting for an internal Russian leadership conflict, I think anyway
