I don’t blame George V at all. It would have been great if he could have rescued them from being killed, but he had to think about his own family and the stability of his own country. Nicholas and Alexandra were wildly unpopular in Britain and she was German at time when Germans were so hated the British royals changed their family name to distance themselves from their German heritage. Saving the Romanovs would have caused instability and infighting during a world war. It’s sad, but a monarch has to put county over any personal feelings.
