The WT fulfills prophecy all right. Just not how we thought.
13 And the word of Jehovah continued to occur to me, saying: 2 “Son of man, prophesy concerning the prophets of Israel who are prophesying, and you must say to those prophesying out of their own heart, ‘Hear the word of Jehovah. 3 This is what the Sovereign Lord Jehovah has said: “Woe to the stupid prophets, who are walking after their own spirit, when there is nothing that they have seen! 6 “They have visioned what is untrue and a lying divination, those who are saying, ‘The utterance of Jehovah is,’ when Jehovah himself has not sent them, and they have waited to have a word come true. 7 Is it not an untrue vision that YOU men have visioned, and a lying divination that YOU have said, when saying, ‘The utterance of Jehovah is,’ when I myself have spoken nothing?”’
8 “‘Therefore this is what the Sovereign Lord Jehovah has said: “‘For the reason that YOU men have spoken untruth and YOU have visioned a lie, therefore here I am against YOU,’ is the utterance of the Sovereign Lord Jehovah.” 9 And my hand has come to be against the prophets that are visioning untruth and that are divining a lie. In the intimate group of my people they will not continue on, and in the register of the house of Israel they will not be written, and to the soil of Israel they will not come; and YOU people will have to know that I am the Sovereign Lord Jehovah, 10 for the reason, yes, for the reason that they have led my people astray, saying, “There is peace!” when there is no peace, and there is one that is building a partition wall, but in vain there are those plastering it with whitewash.’
11 “Say to those plastering with whitewash that it will fall. A flooding downpour will certainly occur, and YOU, O hailstones, will fall, and a blast of windstorms itself will cause a splitting. 12 And, look! the wall must fall. Will it not be said to YOU men, ‘Where is the coating with which YOU did the plastering?’
13 “Therefore this is what the Sovereign Lord Jehovah has said, ‘I will also cause a blast of windstorms to burst forth in my rage, and in my anger there will occur a flooding downpour, and in rage there will be hailstones for an extermination. 14 And I will tear down the wall that YOU men have plastered with whitewash and bring it into contact with the earth, and its foundation must be exposed. And she will certainly fall, and YOU must come to an end in the midst of her; and YOU will have to know that I am Jehovah.’
15 “‘And I will bring my rage to its finish upon the wall and upon those plastering it with whitewash, and I shall say to YOU men: “The wall is no more, and those plastering it are no more, 16 the prophets of Israel that are prophesying to Jerusalem and that are visioning for her a vision of peace, when there is no peace,”’ is the utterance of the Sovereign Lord Jehovah.
