2 major massacres of refugees, chemical weapons in built up areas, heavy artillery used against schools and hospitals, ...
Not wanting to join in the raking up of ancient history again, but for the record:

1. Israel has not massacred anyone.

2. What Jim calls "chemical weapons" are the standard smoke rounds used by every army in the world.

3. Israel would gain nothing by deliberately shelling a school or hospital, so they do not do it.

We have been over all this many times.
