I'm afraid you are right, but he sure had fun trying. In the process he upset all sorts of tight-a@@ academics with all the answers and the keys to that kingdom.
While he may not have "proven" much of what he set out to prove, he did prove (at least in my mind) that man could travel where he traveled, and in the way he did, and that is a remarkable achievement.
In all fairness to Thor, I think we should note that those who disagreed with Thor never proved anything conclusively either. They simply had the weight of "tradition", that anchor to progress which incorporates unsubstantiated speculation in the absence of other answers, and over time becomes known as "settled fact".
The true history of the Lost Tribes of Israel also has to challenge wholly unsubstantiated and agenda-driven "traditional" views of history. And that is now happening.
