Date setting done right

The we can't possibly know crowd don't usually know what a generation is either maybe its stuff we can't know too. But if we add Psalms 90:10 The days of our years are threescore years and ten; and if by reason of strength they be fourscore years, yet is their strength labour and sorrow; for it is soon cut off, and we fly away.

Matthew 24:32 Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh.
Almost all bible teachers believe that this would be Israel becoming a nation in 1948.
And with our previous verse we see a generation is 70 to 80 years. Israel has been a nation over 63 years so we have at most 17 years to go and subtract 7 for the Great Tribulation the saved are raptured before. Because Jesus said all things will be fulfilled in that generation that sees Israel as nation.
