@cicerone imposter,
It is the responsibility of the non-murdering Palestinians who do not reside in Israel to
police the murdering Palestinians among them. Currently they do not even attempt to
police the murdering Palestinians among them.
If the Palestinians who do not reside in Israel want Israel to do the
policing all they have to do is sign a treaty to that effect with the Israelis.
Until the non-murdering Palestinians residing outside of Israel either start policing the murderers among them, or sign a treaty with Israel to do it, the non-murdering Palestinians have no one other than themselves to blame when they are casualties of Israel's attempts to exterminate the murdering Palestinians.
Of course, any treaty between Israel and the non-murdering Palestinians will require that the non-murdering Palestinians agree to recognize Israel's right to exist.
