Am I dreaming or has Keith repeated yet again that Israel is legitimate in bombing children?

You are dreaming.
It is illegal to attack civilians.

He keeps talking of international law yet The UN keeps reiterating that Israel is an aggressor and has no more right than Hamas.

The UN reiterates no such thing, except that General Council resolutions always go against Israel.
You will find no official reiterating such bollocks.

This thread is not about Israel and Gaza BTW.
