Unless you are a Qara'ite or Protestant, you must acknowlege that Moses had successors (Joshua being the first) down to our own day.
Wow, what a horrible argument! Speaking as a Bible believer, I have to hold my nose. Many nations do have historical myths that are widely believed, which provides abundant contradiction to the author's claims that false historical facts cannot come to be generally accepted.
The article doesn't deny the existence of myths. It points out that the Revelation at Sinai is the only time in history when G-d spoke to an entire nation at once. The religions of the nations are based on G-d (or a "gxd" of some kind) speaking to one person or a small group of people. Israel's is the only case of objective national revelation in history.
Moses had the Sinai and Divine Storms, perhaps Moshiach will have the Internet and Divine Servers.
Although I don't agree with Rabbi Eliyahu's conclusion, I do agree with your interpretation of it. He is saying not the Zionists but the anti -Zionists (those who want to disengage) brought down God's wrath on the world.
