For a clue what this refers to see today's Washington Post for an article on rising US casualties.
So anyway, the theory seems to be that if they snip the country into three, at least the Kurds and the Shia'a will be quiet long enough for the troops to be brought home.
Kind of turns that "cutting and running" phrase on its head.
