But Eastern Europe wasn't the entire Jewish diaspora, which was my point. I realize it made sense for a large group, but it couldn't establish itself as universal. It would be excluding a large group that way.
I'm certainly not entering this debate to suggest what was the best course of action, such normative thinking isn't really helpful in a history discussion. However, as a discussion of why Hebrew was the only artificial language to succeed, I think the fact that there was no other mutually intelligible language was a large factor in explaining its success.
I think it was the Israeli satirist http://en.wikipedia.org/wiki/Ephraim_Kishon who once wrote that Israel is the only country in the world where the mothers learn the language from their children.
