He’s wrong about Isreal. The promises were made to a Abraham and to his seed. GALATIANS 3:16 explains that the seed is Jesus Christ. And Galatians 3:36 further clarifies that if ye be Christ’s, then are ye Abramham’s seed, and heirs according to the promise.
Unbelieving Jews are NOT the subject of the promise. Christians are.
How does that grant superiority to the people calling themselves Palestinians?
