"In 2013, Sanders failed to register any formal objection to S. Res 1456 which passed by unanimous consent and sought to award the Gold medal to war-criminal Shimon Peres (the Gold medal is the highest civilian honor bestowed by the U.S. congress).
In 2008, Sanders co-sponsored S. Res 522 that celebrated Israel’s 60th anniversary. To Palestinians, that same day is known as Yawm an-Nakba (meaning “day of the catastrophe”), aptly named to reflect the suffering that Palestinians have experienced since the birth of the State of Israel.
In 2001, Sanders voted Yea to H. Res 34 which “congratulates Ariel Sharon on his election as Prime Minister, and extends to him the best wishes of the people of the United States”. The war-criminal Ariel Sharon, well known as the “Butcher of Beirut”, was responsible for triggering the Al-Aqsa Intifada on September 28th 2000 after his visit to Haram Al Sharif, surrounded by hundreds of Israeli riot police."
