No Jim.
The reliable witnesses do not show Israel as complicit.
Israel acknowledged that people should have forseen events and should have acted sooner.
The UN enquiry found them "responsible" only by virtue of them being the occupier.

There is no compelling evidence for any culpability beyond the above.

If Israel was guilty of all your accusations in would be a pariah.
Decent countries including yours do not regard it as such.
It is all bollocks.
