Laila,
You are allowed to condemn Israel if you like, but you have to include a reasonable argument with this condemnation. The fact that you're Muslim, and some of your Muslim brothers are being killed in the Gaza strip, naturally diverts your point of view towards supporting them. Which is fine, but it doesn't make any sense.
The Palestinian rockets kill and hurt Israelis on a daily basis. I don't even need to provide you with a source; just watch the evening news. But besides that, this conflict doesn't resolve around the number of causalities of both sides. It all boils down to this: Palestinians are shooting rockets, daily, into independent Israeli territories. They are not shooting at settlements - that would be ungainly, as they are likely to miss - they are shooting at large towns instead. Sderot and Ashkelon are two large cities threatened by these rockets, and one day, one of these rockets is bound to carry destructive results - it had happened in the past.
For some time, we have had a truce with Hamas. It was clear that this truce was meant to give Israeli politicians some time to deal with their own, local affairs, while Hamas armed itself once again. During this period of time, and till this very same minute, Palestinians continue to receive humanitarian aid, which is conveyed to them through Israeli territory. They also continue to receive electricity through our electrical stations, as well as petrol and diesel. And yesterday, two Palestinian girls have been killed as a result of a rocket attack launched by their brothers. And guess who handed out ambulances to them, to take care of the wounded.
This fake truce has been broken by Hamas, which has apparently decided that they're armed and equipped well enough to continue murdering Israelis. But this time, Israel had a plan ready, which was flawlessly executed this morning. This plan was a defensive act, not a dirty scheme to murder Palestinians.
The attacks this morning have been carried out in an extremely precise manner, and used as little explosives as possible so as to minimize civilian causalities. It is not our fault that Hamas uses civilians as human shields. This was evident today - when the so-called 'heroes' launching the rockets, couldn't continue to do so from the north of the strip (with a timer, of course!), as the air force was watching. So instead, they retreated to some civilian areas. Lovely.
It is difficult to understand this situation. Until today, I couldn't understand it myself. I live in the center of Israel and never had any rockets landing near my house. But just today, visiting the city of Ashdod to meet some relatives, I was greeted with the first siren that this city has ever had. And trust me, until you've been in a similar situation, you can't understand how people living in the shadow of this threat live.
