Daniel 7:8 I considered the horns, and, behold, there came up among them another little horn, before whom there were three of the first horns plucked up by the roots: and, behold, in this horn were eyes like the eyes of man, and a mouth speaking great things.
There are several interpretations, the one I think is best is that the Antichrist's kingdom will be divided into the ten regions the UN is now dividing the Earth up into. Each kingdom is considered a horn. India has a horn, we saw them just destroy Pakistan's air defense. But the Antichrist is called a "little horn" meaning little or small. I realize there are several Biblically valid interpretations concerning the Antichrist. I would not doubt that his lineage includes someone that would allow us to refer to him as "the assyrian" but I highly doubt that is a reference to a ruler of Syria or Iraq. No I think the best guess is that he will be a ruler in Europe. He can be a president, but he has to also be a prince or king. But here is the thing, he is a "small" horn compared to the three that are removed. A European leader would be considered a "small horn" compared to the US, China and Russia.
But that is not the only basis for this "educated guess". The other is many, many prophecies that indicate a time frame for this age is coming to an end. If the end of the age were still a hundred years away it would be different, but how is it that the US is not mentioned in Revelation (personally I think that The Great Babylon is a reference to the US being destroyed at the start of the seventieth week) and China is also not mentioned (though you can argue that the armies from the East are a reference). Russia is mentioned, they are Gog, but they lead an all or nothing attack on Israel in the Ezekiel 38 war and they are defeated. So those are three horns bigger than a European leader, say Emmanuel Macron (who is also a prince of Andorra). It would explain why they are not mentioned more, because they got removed to make way for the Antichrist.
