>>>The state of Israel purposefully grew the myth of both the danger they were in as well as the legend of their unlikely victory.
To answer your question as to where Rabbi Wein’s observation came in, it because the only three groups who make such claims about the Six Day War are (1) Far far right frum groups (2) militantly atheistic anti religious secular Jewish Groups and (3)anti-Semites.
When Yitzchok Rabin said that “anyone who thinks we should be thanking for our victory is the six day war is mistaken. Is was all out superior planning” that statement was unacceptable in the frum world. Rabbi Shapiro saying it doesn’t make it any better or different. It’s not for no reason that Rabbi Shapiro is such good friends, quotes and appears at so many events with Gilad Atzmon (google the two names together) a guy who makes the typical secular Israeli seem like a tzadik. And it’s not for no reason that both of them are quoted in anti-Semitic literature
