How cool would it have been had the Pope said this prayer at the security barrier:
Hey Lord, remember how we Catholics made every single Jew in the word an object of scorn and derision and regarded them as sheep led to slaughter to be killed, destroyed, beaten and humiliated as punishment for something a handful of Jews, in the distant past, may or may not have done? That sucked. It was wrong. Collective punishment is evil. Therefore, as we Catholics finally repent and atone for that horrible crime, we ask you to help the Israelis reach this understanding and seek to fight terrorism by fighting the terrorists, rather than by forcing an entire population of men, women and children who cannot discern between their right hand and their left hand to suffer for crimes they have not personally committed.
The forgoing is not a criticism of the barrier per se.
