Fine - it didn't occur to me that you would use that sort of argument. Here are some that have more clearly failed:
Ezekiel 26:7-14
"For thus says the Lord: "Behold I will bring upon Tyre from the north Nebuchadnezzar of Babylon, king of kings, with horses and chariots, and with horsemen and a hosts of many soldiers. He will slay with the sword your daughters on the mainland; he will set up a seige wall against you. He will direct the shock of his battering rams against your walls, and with his axes he will break down your towers...With the hoofs os his horses he will trample all your streets; he will slay your people with the sword and your mighty pillar will fall to the ground...they will break down your walls and destroy your pleasant houses... I will make you a bare rock...you shall never be rebuilt, for I have spoken," says the Lord God."
When Ezekiel wrote that around 587 BC, it seemed like it would almost certainly come true; Nebuchadnezzar was laying siege to Tyre with a huge army that seemed overwhelmingly powerful. However, after 13 years of siege he finally gave up and went home. So there is no way that this can ever happen, unless you want to propose that Nebuchadnezzar will be brought back to life so that he can raise an army and siege Tyre.
