"An investigation would show whether or not atrocities were committed. That's a given, isn't it?" Unfortunately not. It'll provide additional evidence which might make it possible to determine what happened. But 30 years and there's still no unambiguous certainty about Bloody Sunday, and that was a much much smaller affair, and better documented at the time.

As for "ethnic cleansing", it doesn't seem that what happened in Jenin falls into that category. (But the reason the people involved were living in refugee camps in Jenin rather than in their homes back in Haifa - that was ethnic cleansing, if there ever has been ethnic cleansing.)

But once again, though I have once again contributed to this thread, I think that if people want to continue discussing this whole issue it'd better be done in a new thread that didn't start off in a way that came across as racist and sectarian.

As Kipling put it:

That which is marred at birth Time shall not mend,
Nor water out of bitter well make clean;
All evil thing returneth at the end,
Or elseway walketh in our blood unseen.
Whereby the more is sorrow in certaine--
Dayspring mishandled cometh not againe.
