When Jesus was speaking of "the END", it was a reference to what the natural Jews thought "the end" was, which was the end of their current "system of things" which was rule by gentiles. So the "end" is a reference to the " end of the gentile times" which ended on November 30, 1947 when the Jews officially came out of exile.

jesus was talking about the temple being destroyed in 70AD. Given the gospels were all written after this, its not prophecy but a warning. Jesus is telling the jews to give up in their fight against Rome. That "end' did happen, they got punished for trying the impossible.
