v3 of Ezekiel's Tyre prophecy says that “many nations” will attack Tyre, “as the sea brings up its waves”. This is relevant because in 586 B.C. and 332 B.C. respectively, Tyre was assaulted by Babylon, and then subsequently by even more nations, united under Alexander the Great (Macedon, Cyprus, Rhodes, etc.). Neither of these facts are disputed by scholars.
But wait, this part of the prophecy failed: Alexander's forces coalesced into just one nation, namely Macedon, so Nebuchadnezzar's army plus Alexander's army made up two nations rather than “many”, right?
v6-11 of Ezekiel's Tyre prophecy say Nebuchadnezzar will destroy Tyre's coastal suburbs.1 This is relevant because Nebuchadnezzar did specifically destroy “Ushu” (Tyre's coastal district).2
v4, 12, 14 of the prophecy say that Tyre's enemies will throw her timbers, stones, and all her debris into the sea (making her a "bare rock").1 This is relevant because:
“The refusal of the Tyrians to surrender led Alexander to connect the isle to the mainland with the construction of a causeway, one of the most difficult marine engineering tasks of that era… The stones of the fresh ruins of ancient Tyre, together with trees limbs, were drawn into the water, and stones and sand were placed on top of them in order to build the mole.” [Yaacov Nir, “The city of Tyre, Lebanon and its semi-artificial tombolo” Geoarchaeology 11 (1996): 235.]2, 3
v4-5 of Ezekiel's Tyre prophecy say that Tyre will be reduced to a humble abode for fisherman.1 This is relevant because, after Tyre (the city) was completely annihilated, Tyre (the land) was resettled by new peoples. To this day, “the causeway still remains, now as a place, as Ezekiel foretold, on which fishermen dry their nets.” [Zondervan Illustrated Bible Dictionary, (eds.) Douglas, Tenney, Silva (Zondervan, 1987), 1493.]
v5, 12 of Ezekiel's Tyre prophecy say that Tyre's enemies will plunder her wealth.1(This does not require that every enemy will get to plunder her). This is relevant because:
E.L. Skip Knox: “Alexander was so furious that this one city had halted his progress for so long, that he gave the city over to plunder and his soldiers sacked it without mercy.” [“Alexander the Great: The Siege of Tyre (333)” online at europeanhistory.boisestate.edu]
v13-14, 19-21 says Tyre will permanently annihilated via the above terrors.1 This is relevant because Alexander intentionally wiped out Tyre and replaced her.2
“Wasn't the city of Tyre rebuilt?
• …Alexander annihilated and carefully replaced Phoenician Tyre with a different new Tyre. (v. 4-5 entail people would live in the area again)
Wasn't it Nebuchadnezzar's forces alone who Ezekiel prophesied to destroy the island?
• …his multi-national army is all that Ezekiel meant by the “many nations”
• …it was only island Tyre that was fortified
• …it said he'd attack “you” (island) and “your daughters” (coastal)
• …in Ezekiel 29, Ezekiel admits his prophecy failed
“Wouldn't the conjunction of Nebuchadnezzar's army and Alexander's army make up only two nations, rather than ‘many’?
