He is too prescriptive and doctrinaire in his assessments. He is tied to a very specific timeline that supposedly started in 1948 with the creation of the current state of Israel. He is not open to other possibilities, such as:
* That this "Israel" is not the prophecied one.
* That time frames cannot be specifically predicted - that even if the real "new" Israel started in '48, that the subsequent sequence of events may take an unknown amount of time.
* That "Israel" may involve either the specific state of Israel or, the state of Israel plus world wide Jewry, and supporters of world wide Jewry.
* The role of the US - so many possibilities.
* Etc.
