“If they’d obey God more they wouldn’t keep getting into trouble.”
That’s a lesson for humanity in general, not just Jews.
Have you read the OT? You keep acting as if the Jews disobeying God is the same as everyone else disobeying God. The Jewish people are His specific called out people of all the world. God never once held other nations to the same standard because He didn't bring them out of Egypt through the sea and through the wilderness into the promised land.
It's like your wife cheats on you and someone comes along and says "well what's the big deal?" It's no different than other wives cheating on thier husbands.
To you it's different.
