Thanks for your reply Fireweaver. It seems only about 50 years before that, England and Germany attacked Russia when they invaded Turkey? (somewhere south of the Crimea), so it would seem they weren't too intimidated. It might have been due to all the crimes the tzar was charged with so of course the Bolsheviks would want to try him supposedly. Now Putin wants all those crimes pardoned and the family has already been canonized by the Russian Orthodox Church.
But it is more understandable in those terms. The USA doesn't appreciate other countries which give safe harbor to certain individuals either.
