Failed prophecy in the bible if one cares to look

[GrandizerII]

Tyre was never a nation in the modern sense. It was a city-state like Athens. There has never been a time when Tyre was completely destroyed or completely uninhabited. In fact, the population of modern Tyre is roughly four times what it was at the height ancient Tyre.

History-1 : Prophecy-nil.

The Nation of Tyre was completely destroyed, as confirmed by numerous secular sources.  There now exists a small portion in the area where the nation of Tyre once stood--a small area called a district.

"Tyre in Later Centuries
Tyre was razed to the ground. It was standard practise for a victorious army to reduce the walls of a conquered city to rubble, lest the city be refortified and again used against them. This was the case with Tyre. Stripped of its impressive defences and denuded of its citizens, proud Tyre, no longer even an island was for a time, only fit for fishermen to dry their nets on the bare rock. . . .

By the end of the 19th century, a population was again beginning to form in what had once been Tyre."

Modern Tyre is a very busy and lively place, hardly just a place "fit for fishermen to dry their nets on the bare rock". I would know.

Anyway, whoever authored that passage probably didn't think about how the world would unravel thousands of years into the future. He was predicting that Nebuchadnezzar, king of Babylon, would completely ruin Tyre.

Ezekiel 26:7-14
"For this is what the Sovereign Lord says: From the north I am going to bring against Tyre Nebuchadnezzar king of Babylon, king of kings, with horses and chariots, with horsemen and a great army. He will ravage your settlements on the mainland with the sword; he will set up siege works against you, build a ramp up to your walls and raise his shields against you. He will direct the blows of his battering rams against your walls and demolish your towers with his weapons. His horses will be so many that they will cover you with dust. Your walls will tremble at the noise of the warhorses, wagons and chariots when he enters your gates as men enter a city whose walls have been broken through. The hooves of his horses will trample all your streets; he will kill your people with the sword, and your strong pillars will fall to the ground. They will plunder your wealth and loot your merchandise; they will break down your walls and demolish your fine houses and throw your stones, timber and rubble into the sea. I will put an end to your noisy songs, and the music of your harps will be heard no more. I will make you a bare rock, and you will become a place to spread fishnets. You will never be rebuilt, for I the Lord have spoken, declares the Sovereign Lord.

That didn't come to pass, and Ezekiel 29:17-20 probably served as an apologetic piece regarding that.

Ezekiel 29:17-20
In the twenty-seventh year, in the first month on the first day, the word of the Lord came to me: "Son of man, Nebuchadnezzar king of Babylon drove his army in a hard campaign against Tyre; every head was rubbed bare and every shoulder made raw. Yet he and his army got no reward from the campaign he led against Tyre. Therefore this is what the Sovereign Lord says: I am going to give Egypt to Nebuchadnezzar king of Babylon, and he will carry off its wealth. He will loot and plunder the land as pay for his army. I have given him Egypt as a reward for his efforts because he and his army did it for me, declares the Sovereign Lord.

This is an apologetic way of saying Nebuchadnezzar failed to completely possess/destroy it, but God had it in his plan to instead give Egypt to Nebuchadnezzar as a reward.
