>That is a great and underused method of evaluating moral judgments and I believe that it’s very suitable in this particular case.
It also dilutes the current and very real responsibilities of the 'effectors'. In saying 'they would have done the same' it becomes very easy to justify the unjustifiable.
I do not have much hope that Palestinians would behave “better” according to any sensible measure of the word.
I would conjecture that many governments would position themselves differently and that criticism would face less obstacles.
In the end it would be as much of a catastrophe.
