Your notion of building houses in the West Bank in "retaliation" amounts to providing an after-the-horrific-murder justification for a policy that didn't have one, besides religious fervor of a supremacist kind. Give your natural revulsion at this horrendous crime another vent-out. If gut rules over reason and heart, then we will justify a collective punishment out of our desperation. Let the shiva be, and let the revulsion have its natural course outside politics. Ose shalom bimromav, hu yaase shalom aleinu, veal kol Israel, veimru amen.
