I haven’t read all the posts and I would like to do so, but I think the biggest kefira is to say the Hashem is not in charge. Even if they prayed for the land of Israel, Hashem can say no as Moshe Rabeinu found out and we find out almost on a regular basis. We can move mountains with our speech and deeds, but ultimately Hashem is in charge and if he didn’t want the State of Israel to be, it wouldn’t have been.
