"Israel answers the question."

Israel determines the baseline.

As a descriptive matter, every state's legal system adopts rules for resolving disputes.

The deeper question is:

Does legal validity automatically imply moral or historical correctness?

Most legal philosophers answer:

No.

For example,

A law may be:

legally valid,

constitutionally challenged,

morally defended,

morally criticized,

all at the same time.

Legal validity and moral justification are different concepts.
