If the Pope and bishops obeyed Our Lady and consecrated Russia, there would have been no Bolshevik revolution in 1917.  No Communism, then no National Socialism.  Thus, we would not have had a WWII.

But world leaders didn't choose Our Lady.  They rejected God's message and picked Communism as their alliance and support.  So, now you have to live with the consequences.  

It's not too late.  One can convert to the Catholic faith and avoid hell.  One can choose to pray the rosary.  How about it?  It's not too late.
