It is a terrible tragedy and I am sorry for the death of all the innocents.
I know this baby was really killed but in some cases pictures are posted as propaganda as seen in the following link. Dead child in Syrian fighting-reposted as Palestinian child in Gaza.

Sadly it is more often true than not. There are many pictures of Israeli deaths but you are not likely to see them posted in our media.
What will it take to keep them from fighting?
There is no answer, not now. But I do want to say before there was a Jewish State, before the holocast, the mullah in Jerusalem in the 1920s called for a jihad against the Jews living in Israel. The Arabs rioted and killed their Jewish neighbors they had lived peaceflly with for ages. They slaughtered the old people and the babies too.

I have no doubt that many Palestinians would like to live peacfully in Israel and I know that many Israeli Jews want the same.
Iranian backed Hamas and the Egyptian ruled Muslim brotherhood are evil and will kill their own people for calling for peace. They will never rest as long as one Jew lives in the land. They make it quite clear.
The Israeli government in my opinion is far from perfect and I do not defend all actions or policies by any means. Having said that they are doing what any country must do under attack.
