Regarding what Rav Chaim said: If that is true, why is there more Torah being learned in Israel right now than in any other country, or at any other period in the history of klal yisrael?
Regarding what rav elchonon h”yd said: Perhaps this will happen, but Israel has not yet lost a war (except maybe yom kippur)- that is an amazing track record considering hundreds of millions of Arabs want Israel wiped off the map.
Also, the establishment of Medinat Yisrael fulfilled several very important nevuahs about keitz hayamim and the future geulah. Yeshayahu 41:18-21 says the desert land will one day bloom again. Yechezkel 37:11-13 predicts that all the Jews will return to eretz yisrael in a massive kibbutz galuyos. Both of those things have started to happen and are continuing to happen every second of modern Israel’s existence.
So go call our neviim apikorsim r”l straight out, because that is what you are implying.
