Since its founding in 1987, Hamas has used the murder of civilians to spoil any chance of a two-state solution. In 1993, its suicide bombings of Israeli civilians were designed to destroy the two-state Olso Accords that recognized Israel and Palestine. This month, the Hamas terrorists unleashed their slaughter in part to undermine a peace with Saudi Arabia that would have improved Palestinian politics and standard of life, and reinvigorated Hamas’s sclerotic rival, the Palestinian Authority. In part, they served Iran to prevent the empowering of Saudi Arabia, and their atrocities were of course a spectacular trap to provoke Israeli overreaction. They are most probably getting their wish, but to do this they are cynically exploiting innocent Palestinian people as a sacrifice to political means, a second crime against civilians.
