ZD,
Nothing you have written in anyway indicates that R Chaim Ozer made a mistake. The question really is why you keep prattling on when you are wrong. Considering your self infallible is not a Jewish trait, rather it is a catholic trait.
Small facts that you are conveniently omitting;
The people who remained in the towns the Yeshivas ran from were massacred before those in Vilna. So those who fled to Vilna lived and learned longer.
Whole yeshivas were in fact saved from the holocaust.
But facts were never a strong point in any of your arguments, they just tend to get in the way.
If you like, we can post that on Wikipedia for you.
