Fellow Christian here, I want to put forward my interpretation of Daniel 7 and hope anyone (Christian or not) can help me poke holes in it.
My claim is that the Little Horn of Daniel 7 is Titus.
Daniel 7 tells a vision of four beasts that represent four kingdoms (v. 23). The first is a lion with wings. This has almost universally been understood as a symbol of the Babylonian Empire, the dominant power at the time Daniel claims to be writing. The second is a bear with three ribs in its mouth. This would likely refer to the Persian (Achaemenid) Empire, and the three ribs referring to the territories it gained in its ascendancy: Babylon, Media, and Lydia. The third is a leopard with four heads, this would represent the Greek (Macedonian) Empire under Alexander, with its subsequent division into the kingdoms of Ptolemy, Cassander, Lysimachus, and Seleucus.
So far these are all somewhat uncontroversial claims. Many scholars believe that Daniel was written after the division of the Macedonian Empire. If that's true, then none of these are genuine predictions of future events. What comes next would be truly predictive prophecy.
The fourth beast is non-descript, only that it has ten horns. This fourth beast would logically be the next major political power in the area, the Romans. The ten horns, Daniel says, "As for the ten horns, out of this kingdom ten kings shall arise." (v. 24) If we reckon these horns as Caesars, beginning with Julius, then we could say they represent Julius, Augustus, Tiberius, Caligula, Claudius, Nero, Galba, Otho, Vitellius, and Vespasian.
But the prophecy continues that another (11th) "little horn" arises, uproots three other horns, and for "a time, two times, and half a time" makes war against the people of God. The eleventh caesar is Titus. And it seems he fits this description perfectly.
Titus succeeded his father Vespasian, and thus was the eleventh Caesar. He, as commander of the army, had overthrown the three emperors prior to his fathers reign: Galba, Otho, and Vitellius, in the so-called “Year of the Four emperors.” And why should he be considered a “little horn” and different from the others? Because he was awarded the title of Caesar, along with this father Emperor Vespasian, but did not become emperor until after his father’s death. So he was the first of the ten previous caesars who was not also the emperor.
“He shall speak words against the Most High, and shall wear out the saints of the Most High, and shall think to change the times and the law; and they shall be given into his hand for a time, two times, and half a time.” (v. 25) This "time, two times, and half a time" is universally acknowledged to refer to a period of three and a half years. And it was Titus who led the Roman army into Jerusalem during the Jewish War, which from the arrival of Titus in Israel to the destruction of the Temple spans exactly 42 months, or three and a half years, from March of AD 67 to the fall of Jerusalem in September of AD 70.
And Titus also, spoke “words against the Most High,” when, during the destruction of the Temple, as the Talmud records it: “Titus said, “Where is their God, the rock in whom they trusted?” This was the wicked Titus who blasphemed and insulted Heaven. What did he do? He took a harlot by the hand and entered the Holy of Holies and spread out a scroll of the Law and committed a sin on it. He then took a sword and slashed the curtain.” And that he changed “times and laws” is clear because with the destruction of the Jewish Temple the ordinary observance of the law and of the Jewish feasts were never to be observed again.
