This will give a better explaination. Got to remember that the ancient Roman empire also went into what was and is now the Middle East.

Isaiah 10 and 14 are about the Medes and Persians destroying Israel, not the anti-Christ
and Rome ruled the Medditerranean, not the middle east, they ruled all the countries that were on the water, all othe conquests were temporarily
also, this author made the comment that western europe fell and wasn’t under rome, he forgets England, France, holland and Germany, Spain was muslim for a while, but they were thrown out 500 years ago
