"Today I saw an extraordinary film named "The Other Son," about Israeli and Palestinian baby boys who were mistakenly switched at birth.

The switch is discovered when the Israeli boy is turned down by the army because his blood type doesn't match his parents. We have two boys accustomed to think of themselves as Jewish or Palestinian, and they are legally each other."
