Daniel 9.27 - What Is It Talking About

Some people are thinking/talking about 2021 as the year of the Rapture/TRIB(start of).
They take 1948 (return of Israel) then you add 80 years (Psalms 90.10)= 2028. Then subtract 7 = 2021.
But that WHOLE IDEA of 7 years for the TRIB is BOGUS !!  
Why do i say that??
 I did a video on the length of TRIB = 5 months(Revelation 9.5,10).
But i need to do more such.
For now let me just say Dan 9.27 is NOT about endtime!!  
It follows 9.26 about the slaying of Messiah.
So, logically, the curses of Deuteronomy 28 should follow in Dan 9.27.
For on one level that execution was total abomination - rejection of "prophet like me" that Moses predicted(Deuteronomy 18.18).
It was the "time of VENGEANCE" that Christ spoke of(Luke 21.22).
 What's my point?? That the curses of the Law of Moses(Deut.28)=Dan.9.27.
 So the "the Covenant with many" = SHORTHAND for the CURSES of the Covenant of Moses.  
So the 7 years = the 7 years of the Roman-Jewish War of AD 66-70/73.  
It is 66-70 without counting Masada in 73 as the last battle of that war.
But if we do count Masada, we get a 7 years war !!
 And Encyclopedia Judaica DOES offer 66-73 as an alternative length of that war (rather than 66-70).
 From mid 66 to mid 73 does add up to 7 years, ok??  
So there is NO NEED to apply the 7 years in Dan.9.27 to the endtime TRIB.
 Tell me - in your comment - if i make or dont make sense.
