There can be no dual fulfillement of Matthew 24 as claimed by the WT. Because Jesus said to those standing infront of him "then there will be great tribulation not seen since the worlds beginning until NOW and would NEVER be seen again".

So he said himself it would never be seen again after the 1st century generation experienced it att he detruction of Jerusalem and the Temple.
