Hmm, let me see; during this recent exchange, how many Israelies were killed or injured? You mention 1 elderly lady, so that is 1 that I have heard of so far. You also mention 20 civilians in Gaza, but in the same breath imply that it is probably their own fault. Now, if you step back a bit and look at what you are saying, can you understand why so many people in the rest of the world feel less than convinced of your sincerity?
You guys enjoy the protection of the US, you have overwhelming, technological advantages over your opponents, you have throughout history shown little to no interest in finding peace with your neighbours, and a large proportion of people outside of Israel feel that you are engaged in shameless landgrabbing, apartheid and collective punishment of the Palestinian population. And as your own words demonstrate, you don't actually give a sh*t about it; but you still expect the rest of the world to feel sorry for you.
This is what I think should happen: the US should withdraw all military and economic support from Israel with about a year's warning. Then you guys will have a bit of time to try to find another way to deal with your neighbours - I suspect you will become really nice and open to sincere negotiations and find a solution that is sustainable in the long term, instead of being the bully hiding behind America's skirts.
As a side note: I am not an anti-Semite. For one thing, I don't think the state of Israel are worthy representatives of Judaism (just like 'Islamists' are not Muslims), and any way, Jews are not the only Semites.
