Satan started with the Greeks. How do you know Rome won't be buried under lava at the 6th Seal world changing event? Italy has 3 active volcanoes. If those mountains are moved where does that lava go? Why do you think it will be a Roman Empire? What about Africa, Australia, South America, India, China, and Indonesia along with Japan?
I've been stating my belief about this a little while--you may not yet know. For me, Dan 2 and 7 speaks of a 4th kingdom that will end the age. But it appears that there are early and later stages of the same kingdom. That would be the ancient Roman Empire, and a latter-day restoration of a European Empire.
When God passed His earthly, temporal Kingdom from Israel to the Gentiles, it went to the Roman Empire, which became Christian by the time of Theodosius. England and Ireland became Christian outposts of Roman Catholicism, as did the kingdom of the Franks. Later, this kingdom expanded to include the Germans, the Scandinavians, and in the Eastern Roman tradition new territories were added, including the Eastern European countries and Russia. In modern times, this Roman Christianity has now expanded into the Americas, as well.
So European Christianity is the outgrowth of Israel's original theocracy. And as Israel ultimately lost their theocracy due to their apostasy, we expect to see the same in European Christianity, and are seeing it.
Before Europe is judged, though, the pagan empire will be reestablished in place of the dominance of Christianity. This is what Christ will come back to judge and to destroy.
