I hate to be the teller of bad news, but the Russian pronunciation of Caesar is Czar, and the term Caesar is used for the term dictators. The Russian Czar lived in the 20th century, not in the time of Nero. The term Kaiser, is the term for Caesar, such as dictator, who was defeated along with the Ottomans at the battle of Megiddo, which was located just north of Jerusalem, in the 20th century, not in the time of Nero. The 42 months of the "beast" were when the "beast" was given "authority to act". The "saints", not the "Christians", will be under the thumb of the "beast"/nations/Gentiles, until the "end of the age" (Daniel 12:7-13) & (Hosea 5 & 6), which would be right about when Israel became a nation right after the Hitler dictatorship of Germany, a vestige of Rome and her paganism, was crushed in the 2nd world war. The vestige of Russia, combined with the clay Edom, were crushed together in the 1967 Israel war, when both the Russian advisors and the Muslims were crushed together to set up the revised Jerusalem (Joel 3:1) (Daniel 2:34). You should find the PBS narrative on Nero, and revise your thinking.
