The prince who shall come, comes from the people who destroyed the city and temple - the Romans. Rome is in Europe.
Which passage are you talking about here?
The only passage I can find about a king destroying the city; is a parable Jesus tells in Matthew 22. But in that context; the king who sends his armies and burns up the city is God Himself.
Isaiah 11:23 is the same context. He who destroys the city is God Himself.
Rider on a white horse imagery is seen in Zachariah and Revelation.
Zachariah 6:3-6, Revelation 6:2, Revelation 19:11-14.
In all those contexts; that rider is Christ.

Daniel 8:9. Time of the end, following Gog/Magog.
Daniel 8:
9 And out of one of them came forth a little horn, which waxed exceeding great, toward the south, and toward the east, and toward the pleasant land.
10 And it waxed great, even to the host of heaven; and it cast down some of the host and of the stars to the ground, and stamped upon them.
11 Yea, he magnified himself even to the prince of the host, and by him the daily sacrifice was taken away, and the place of the sanctuary was cast down.
12 And an host was given him against the daily sacrifice by reason of transgression, and it cast down the truth to the ground; and it practiced, and prospered.
13 Then I heard one saint speaking, and another saint said unto that certain saint which spake, How long shall be the vision concerning the daily sacrifice, and the transgression of desolation, to give both the sanctuary and the host to be trodden under foot?
14 And he said unto me, Unto two thousand and three hundred days; then shall the sanctuary be cleansed.
…
23 And in the latter time of their kingdom, when the transgressors are come to the full, a king of fierce countenance, and understanding dark sentences, shall stand up.
24 And his power shall be mighty, but not by his own power: and he shall destroy wonderfully, and shall prosper, and practice, and shall destroy the mighty and the holy people.
25 And through his policy also he shall cause craft to prosper in his hand; and he shall magnify himself in his heart, and by peace shall destroy many: he shall also stand up against the Prince of princes; but he shall be broken without hand.
26 And the vision of the evening and the morning which was told is true: wherefore shut thou up the vision; for it shall be for many days.
Herod the Great:
These two passages are somewhat parallel to each other. This "king" and "little horn" are Herod the Great. Herod the Great was of Greek ancestry, although he really wanted to believe he was the Messiah (and he wanted other people to believe he was the Messiah too).
He magnifies himself against the "Prince of the Host" and against the "Prince of Princes". the Prince of the Host and the Prince of Princes is Jesus Christ.
By him (King Herod) the "daily sacrifice is taken away" and "the sanctuary is cast down". He also sets up the "transgression of desolation" and is "broken without hand". This transpires in the course of "2300 days" and there are "1290 days" between the sacrifice taken away and the abomination set up.
So, what does this all mean?
Herod became client king of Judea in (elected by the Roman senate) in 40 BC. In 19 BC, he began reconstruction on the temple. He tore the entire reconstructed Solomon's temple down and totally rebuilt it. It was rededicated 10 years later in 9 BC; although we don't know when, we know it was before Passover.
Around about Passover of 9 BC (or 8 BC - depending on which calendar we are talking about - the "sacred" or the "secular"; because these calendars started 6 months apart) comes John the Baptist's father "in the course of Abia". (End of March) July of that year, John is conceived. Six months later, Jesus is conceived. About Passover of 8 BC, John is born. Six months later; (which would have been right after the secular new year of 7 BC) during the feast of tabernacles, Jesus is born. (End of September.)
Joseph, Mary and Jesus stay in Bethlehem for 2 years. The Magi show up probably around the fall of 5 BC. Mary and Joseph take Jesus to Egypt. Herod dies in the spring of 4 BC. They return from Egypt in the summer time of 3 BC.
The time span this takes place in is 2300 days. I.E. - 6 years and 4 months.
Now; the first communication from God in 400 plus years, comes to John the Baptist's father, Zechariah while he's in the temple. (We'll say Passover of 8 BC because we'll use the sacred calendar. This would have been the beginning of the year.) Roughly a year later John is born. 1.5 years from the angel coming to Zechariah, Jesus is born. 2 years after Jesus is born; Herod kills the babies in Bethlehem.
This time span is 1290 days. I.E. - 3.5 years. (Daniel 12)
So what does "take away the daily sacrifice" and "set up the abomination that causes desolate" mean?
First off, we have to define terms. The word "sacrifice" is not in the Hebrew. "Daily" in this passage is best translated "continuous" or "ceaseless". "Take away" means to "magnify". I have no idea why they translated these verses the way that they did.
11 Yea, he magnified himself even to the Prince of the host, and by him the ceaseless exaltation and the place of the sanctuary was cast down.
12 And an host was given him against the ceaseless by reason of transgression, and it (the host) cast down the truth to the ground; and it practiced, and prospered.
13 Then I heard one saint speaking, and another saint said unto that certain saint which spake. How long shall be the vision concerning the ceaseless and the transgression of desolation, to give both the Holy One and the host (army) to be trodden under foot?
Now this hearkens to Jesus making reference to "destroy this temple and I'll raise it on the 3rd day". He wasn't talking about a building, he was talking about his body.
14 And he said unto me, Unto two thousand and three hundred days; then shall the sanctuary be vindicated.
Jesus was "vindicated" of Herod the Great, when He returned from Egypt.
Now looking at this translation, it makes a whole lot more contextual sense. "Daily sacrifice" is a poor translation because Herod didn't take away the daily sacrifice, as was related to animal sacrifices; God took that away as soon as the Messiah was conceived; because He was the final sacrifice.
So, moving on from Jesus's birth to Herod trying to kill Him when He was two; this is where the "abomination that makes desolate" was set up. The first announcement that the Messiah was coming, was made by the angel when he appeared to John the Baptist's father. 3.5 years later, the coming of the Magi announces to the nation that the "King of the Jews" is born.
This makes contextual sense and fits into the 1290 day, as well as the 2300 day time table(s); both connected to the same king who "understands dark sayings".
