While that applied to Israel when she was the nation of God, and it explains why there are so many of Israels enemies still roaming the earth; for refusing His orders, to utterly destroy her enemies as she was going in to possess the land; it doesn’t apply today. The command to Israel today is to believe on the Lord Jesus Christ, just like every other person who God will save from the wrath to come.
Just because Israel is God’s people, doesn’t mean He will not continue to judge her for rejecting their Messiah, He still has His covenant with them, which He never broke, but they need to fall down on their faces before Him and repent; not just presume He will forbear with them, do what they ask, without a change of heart, for their rejection:
“37“Jerusalem, Jerusalem, who kills the prophets and stones those who have been sent to her! How often I wanted to gather your children together, the way a hen gathers her chicks under her wings, and you were unwilling. 38 Behold, your house is being left to you desolate! 39For I say to you, from now on you will not see Me until you say, ‘BLESSED IS THE ONE WHO COMES IN THE NAME OF THE LORD!’”Matthew 23
Yes, he will Judge them, but only HE can.
I’ve been thinking on the points you’ve made, and I agree.
Israel WAS His chosen people.
Even if they followed the commandments to kill every last man, woman and child, I still don’t see God blessing them as His New Covenant supersedes the Old Testament commands.
