Yes, in war they say you can do anything

So, here is this event::

aths-as-israeli-tanks-shell-gaza-hospital-2014721124111171397.html

The question is this

Even it it were legal to shell a hospital

is this a legitimate and sane thing to do?

You can see how insane this war is becoming.

It reminds me when the Congo was first given its independence and there was the rebellion in Katanga.
It was war.

But was it legitimate and sane thing to rape the Catholic nuns:?
