So, the basic premise remains unchanged: God starts the GT by destroying religion.

How will the great tribulation begin? The book of Revelation answers by describing the destruction of “Babylon the Great.” (Rev. 17:5-7) How appropriate that all false religion is likened to a prostitute! ... But who will destroy the harlotlike organization? Jehovah God will put “his thought” into the hearts of “the ten horns” of the “scarlet-colored wild beast.” These horns represent all the present political powers that give support to the United Nations
If this is to parallel 66 - 70 CE, then God brought that tribulation, and will bring the GT.
What purpose would these serve, as "the door" of salvation has been shut? Would this not mean that the suffering during these tribulations was (will be) intentionally inflicted by God?
