It is impossible for a Preterist to explain how "all these things" occurred in 70 AD.
One that totally debunks Preterism is verse 14,
"And this gospel of the kingdom will be preached in the whole world as a testimony to all nations, and then the end will come."
Preterist quote Colossians 1:23 as proof that the gospel HAS BEEN preached throughout the whole world. Either Paul was mistaken, or the bible contradicts himself, or the Preterist interpretation "sans hermeneutic" is flawed.
I use the KJV because it's the best version that's tied in with the Greek and Hebrew Lexicon. The KJV does have mistakes and Colossians 1:23 is proof.
The word HEAR is mistranslated HEARD, and the word HAVE is NOT in the original text! NO HERMENEUTIC, NO TRUTH!
This is how it's worded in the Textus Receptus which the KJV was transalted from...
IF-SURELY YE-ARE-ON-RAMAINING to-THE BELIEF HAVING-been-foundED AND SETTLED AND NO beING-after-STIRRED FROM THE EXPECRATION OF-THE WELL-MESSAGE OF-WHICH YE-HEAR THE one-BEING-PROCLAIMED IN EVERY THE CREATION UNDER THE heaven OF-WHICH BECAME I PAUL THRU-SERVitor.
You can check for yourself.

LET ME BREAK IT DOWN FOR YOU...Better translated...
If surely you continue to remain grounded and settled in the faith, not being stirred up and moved away from the hope of the gospel,
which ye hear being preached to every creature under heaven; which I Paul am made a minister.
Another one is verse 21 "For then there will be great distress, unequaled from the beginning of the world until now --
and never to be equaled again."
KJV - "For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be."
I can probably list over a dozen historical events that outdid the 70AD destruction of Jerusalem. I should not have to take the time to prove that but if I have to I will.
Preterist even have an outrageous explanation for Verse 7&8. Every time I read them I chuckle!
"Nation will rise against nation, and kingdom against kingdom. There will be famines and earthquakes in various places. All these are the beginning of birth pains."
Sounds like birth pangs BEGAN and ENDED upon the earth pretty quick in 70AD!
My conclusion is that the Preterist view is fully fabricated and in denial of God's Prophetic Word. Preterism denies and distorts over 1,000 verses of prophecy, the entire book of Revelation, and dozens of chapters. Their answer to every prophecy is, "it already happened."
