Sen. Schumer is simply acknowledging the fact that Jews have a deep historical tie, thousands of years old, to the land of Israel. The Palestinian Authority routinely denies Israel's right to exist, and thus don't allow for any serious peace agreement to be reached. I don't defend Chuck Schumer on many things, but he is not wrong in this case.
No they don't.
I should have been more clear - The PA routinely denies Israel's right to exist as a Jewish state, which is to deny the Jews their historic homeland.
No they don't. Not for the past 25 years. Read the Oslo Accords.
