The issue that I always point people toward when I explain how I saw this viewpoint is the note about how it puts the worst judgment to ever occur under the canopy of the immediate years following the cross. One generation away. 40 years. AD70 took place within a generation's span of time after the cross.
The worst tribulation occurred then because the crime of the cross was the worst crime. The punishment fits the crime. For there to be greater tribulation in our future is for there to be something worse than the Lord's own people, his bride Jerusalem (
Ezekiel 16), crucifying Him, and adulterating with Rome's Caesar as her king instead and crying out Caesar's name at the cross!
And stats show that the amount of people in the world at that time compared to any atrocity in history since then gives the greater percentage per capita of tribulation on earth in AD70.
And this makes prophecy and the doom and gloom of judgment focus on the cross more than any other view.
