Just Keep the Faith, and you will save your soul.
If keeping the faith while believing the Pope can be a non-Catholic that is news to me, but God will be your judge, not I.
Don't worry so much about Russia just Trust that God knows what He is doing and never try to tell God how to work out this crisis. That is a no, no!
Remember the Papacy will never fail us, the office will always be there, Jesus Christ has always been the head of His Church. Just as Jesus Christ has risen from the dead so it will be with the Church, look ahead to the days when the Church will rise again. The True Church can not teach error, a True Pope can not become an enemy of Christ. The Pope is the solution, not the problem as I understand from your OP.
Mario Derksen in the last issue of "The Four Marks" explains the Great Apostasy is an apostasy from the Church and the Vicar of Christ, not of the Church or the Vicar of Christ. The shepherd is struck; he is not doing the striking! Pope Pius IX, we see that he describes the apostasy as consisting precisely in a failure to adhere to the Supreme Pontiff and his Magisterium; and so he proposes as the remedy, or as a preventative measure ever greater fidelity to the Holy See, not resistance against it: Maria Derksen further explains ... "This is how we prevent or escape the Great Apostasy: by ensuring we adhere ever more firmly to the Holy See, not by resisting it."
