When I touched my hand against the Western Wall and placed my prayer between its ancient stones, I thought of all the centuries that the children of Israel had longed to return to their ancient homeland. When I went to Sderot and saw the daily struggle to survive in the eyes of an eight-year-old boy who lost his leg to a Hamas rocket, and when I walked among the Hall of Names at Yad Vashem, I was reminded of the existential fear of Israelis when a modern dictator seeks nuclear weapons and threatens to wipe Israel off the face of the map - face of the Earth.

My God, Donald Trump is unfit! He's ill-tempered, he's unsuited, he is not qualified, he's unsuited to be president.

There's a little perspiration involved in bringing about change too. That you have to be organized, that you have to vote even when it's not exciting.
