Ezekiel 17. Is the king of Israel obligated to obey international law?

Ezekiel 17:17
And we see there that God was angry with him for flouting what was then something in our language called international law and making a covenant with Egypt and not with Babylon, and therefore woe and woe.
If it is not in the best interests of the people of Israel, whether security, economic, religious, identity-related, etc., and he is making the wrong decisions…
If he is a ruler of the Natihoz type, then the claim should be written about that.
If he is mistaken, then what is the claim?
Apparently, this is how the scripture was simplified, that there is no claim at all about what he/his advisors believe is good for the people of Israel, not whether they were mistaken or misled or simply negligent.
But only if he did not obey international law (blasphemy against God?)
Am I right?
