Following Anwar Sadat"s visit to Israel in 1978, Perry was one of the leaders of the 348 Israeli military reserves officers petition urging Israeli Prime Minister Menachem Begin to continue with the drive for peace. This petition led to the creation of Peace Now, a movement dedicated to raising public support for the peace process. Throughout the years Perry has opposed Israeli settlement in the West Bank, which he perceives as being immoral and an obstacle for the possibility of peace with the Palestinians.
