A number of times in history, Israel has turned against God and He has put the Jews out of their place. But they have not been utterly destroyed. Now it appears that Israel is refusing to obey our Messiah Jesus; so they could be put out, but not utterly destroyed, unless God simply decides not to have this happen.
Deuteronomy 4 and Deuteronomy 28 Seem to disagree with you:
Deut 4:26
I call heaven and earth to witness against you this day, that you will
utterly perish from the land which you cross over the Jordan to possess;
you will not prolong your days in it, but will be utterly destroyed.
Deut 28
15 “But it shall come to pass, if you do not obey the voice of the Lord your God, to observe carefully all His commandments and His statutes which I command you today, that
all these curses will come upon you and overtake you:
20 “The Lord will send on you cursing, confusion, and rebuke in all that you set your hand to do,
until you are destroyed and until you perish quickly, because of the wickedness of your doings in which you have forsaken Me.
24 The Lord will change the rain of your land to powder and dust; from the heaven it shall come down on you
until you are destroyed.
27 The Lord will strike you with the boils of Egypt, with tumors, with the scab, and with the itch,
from which you cannot be healed.
29 And you shall grope at noonday, as a blind man gropes in darkness; you shall not prosper in your ways; you shall be only oppressed and plundered continually,
and no one shall save you.
45 “Moreover all these curses shall come upon you and pursue and overtake you,
until you are destroyed, because you did not obey the voice of the Lordyour God, to keep His commandments and His statutes which He commanded you.
48 therefore you shall serve your enemies, whom the Lord will send against you, in hunger, in thirst, in nakedness, and in need of everything; and He will put a yoke of iron on your neck
until He has destroyed you.
49 The Lord will bring a nation against you from afar, from the end of the earth, as swift as the eagle flies, a nation whose language you will not understand, 50 a nation of fierce countenance, which does not respect the elderly nor show favor to the young. 51 And they shall eat the increase of your livestock and the produce of your land,
until you are destroyed; they shall not leave you grain or new wine or oil, or the increase of your cattle or the offspring of your flocks,
until they have destroyed you.
61 Also every sickness and every plague, which
is not written in this Book of the Law, will the Lord bring upon you
until you are destroyed.
63 And it shall be,
that just as the Lord rejoiced over you to do you good and multiply you,
so the Lord will rejoice over you to destroy you and bring you to nothing; and you shall be plucked from off the land which you go to possess.
