Regarding your point #2, it was not some innocuous survival idea. The Zionists wanted Jews to be accepted as goyim so after Jews turned down Herzl’s idea of baptism CH”V, they came up with the idea of converting Judaism itself into a goyish Nationalist faith instead.
Regarding the majority of (or even any) “Gedolim being for [the State]”, I have already (at least twice in this thread) explained how this is not the case.
As to Hashgacha post WW-II, even the Brisker Rav is quoted as saying that the Balfour Declaration (even before WW II) was a “smile” from heaven. Unfortunately, the Zionists (and, seemingly, the B”D of Klal Yisrael, as you keep mentioning) turned that smile into the disaster that was and is the State of Israel rather than the true geulah.
