one thing to remember, each beast has to it parts of the beast it conquered.Well, like I said, some apply the final beast kingdom being a revived Roman empire, just because of the mention of iron in the feet of ten toes. Others don't see the final beast kingdom being different from the previous beasts either, like you for example. Yet it will be 'diverse', or different than all those previous to it. And that idea of the final one having all the pieces "together" when Christ comes to smite it upon its feet, is actually very telling. That's why I asked that question.
Each one of the 5 pieces of the beast image statue in Daniel 2 are to be in operation when Lord Jesus comes. That means a revived Babylon style empire, a revived Medo-Persia style empire, a revived Grecia empire, a revived Roman empire, and the final piece, the feet of part iron mixed with clay will be.... ??? The answer to that last beast location should be easy for those that grasp Daniel about the "abomination of desolation".
The final form of the beast will have parts of all four.
one of the biggest reasons people call the final beast rome is in Dan 9. the people of the prince who is to come, will destroy the city and sanctuary.
the people of the prince to come did that in 70 AD.
the prince will commit the abomination of desolation that Jesus mentions in Matt 24.
The people were rome
the future prince than will be from some form of an empire which is roman in nature, at the leasr. he is a roman prince. although the empire might not be called rome.
