Israeli murder justifications

How does Israel explain the executions, the shooting of Palestinians point blank in cold blood? How does it justify Israeli soldiers shooting Kassab Shurrab with five bullets across the chest as he came out of his car with his hands to his side, especially as one of the Palestinian hostages sitting blindfolded by the soldiers heard the commander tell the soldier in Hebrew to shoot the civilians that were driving down the road. What about the two daughters of Khaled Abed Rabbo, Amal, age 2, and Suaad, age 7, murdered by an Israeli soldier using a semi automatic rifle before their father 's eyes as the other Israeli soldiers ate chips and chocolate? Let us not forget about Sameer Rashid Mohammad Mohammad, a 43 year old UNRWA worker, who was separated from his family by Israeli soldiers and taken to a separate room and shot in the chest? For four days after killing Sameer, Israeli soldiers held his family hostage and would make the family prepare the murdered Sameer food. Only when the Israeli soldiers left their home, did Sameer's children see that their father was executed and by their father's dead and bleeding body were piles of food. How about Farah al-Halo, 1.5 years of age, who was shot in the stomach when her family was forced to evacuate from their home at 6:30 PM by Israeli soldiers who assured them of their safety? Only 50 meters down the road they were shot at by other Israeli soldiers. Farah, with her intestines spilling from her stomach, died on the side of the road a few hours later as the same soldiers that had assured their safety watched.
