“He says ‘a divided Iraq will not be a peaceful Iraq.’ …Archbishop Sako fears that possible plans for a Christian safe haven on the Nineveh plain will not succeed. He said: ‘They would have their own territory, but to be viable, the idea of a protected zone, a safe haven, which is viewed sympathetically by the Kurds and even the Americans, needs an end to the violence and remains in any event, a dangerous plan. The Nineveh plain is largely surrounded by Arabs, and Christians would serve as a useful and undefended buffer zone between Arabs and Kurds.’”
In other words, Christians would be caught in the cross-fire between Arabs and Kurds, unless something is done to curb the violence.
"According to the archbishop the best solution is religious freedom:" ‘In my opinion it would be preferable to work at the constitutional level and each area to guarantee religious freedom and equal rights for believers of all faiths throughout the land, including Christians, who can be found everywhere.’
Note: San Diego County, where I live, has one of the largest concentrations of Iraqi Catholics outside of Iraq. They are known as Chaldean Catholics, and they use Aramaic as their liturgical language. That is the language Jesus Himself used. It would be a shame for Iraqi Christians to be purged from their country.
