Excellent question. What you will notice is that those who hate the Palestinians will tell you that when the IDF bomb cars and kill infants, women and children, it is "payback" and is justified because some bozo strapped on a bomb and killed the same in a market square. If it's wrong for one side it's wrong for both. Not however, in the bizarro world of the "Israel never does anything wrong" crowd.
'The country recently expanded the number of people allowed to have gun licenses. Israelis are flocking to gun shops to buy weapons or trade the guns they have for bigger ones. Even opponents of loosening gun laws have dropped their objections, at least for the moment. "You cannot ignore the situation," said Gali Etzion, a lawyer for Na'amat, a woman's organization that has in the past opposed liberalizing laws on gun ownership. Until earlier this year, private gun licenses were limited to people in the army reserves who held the rank of colonel or higher, or to people who worked or lived in specified dangerous areas. Hazan, for example, is a shoe dealer whose work has taken him to the West Bank.'
If Palis don't want their innocents killed, then they need to fight like men and stop hiding behind the ones the claim they want to protect.
Your refusal to hold Palis responsible, and insisting on blaming the Israelis at every turn shows your being lead by bias rather than morality.
You are mischaracterizing the Israeli position. They never call it payback and justify it on the basis that this was done to them. They call it a tragedy that civilians were harmed when their targets were terrorists. If a child is killed, believe me, there are no celebrations with people passing out candy and waving their arms in jubilation. If any Israeli soldier behaves cruelly, he is identified and brought to justice. Israeli terrorists end up in jail. Palestinian terrorists end up being worshipped and their survivors rewarded for their "martyrdom." This would NEVER happen in Israel. That is the difference.
