I think they're not going far enough in their warnings, and a sustained war in the Middle East could push the world into a depression, and literally break the economies of the world, causing severe unemployment, massive loss of small businesses, and a total collapse of the financial and stock markets. This war was unnecessary, it was a war of choice, it was poorly planned, it happened at the wrong time, and the repercussions should have been expected but weren't, because the planners are of such low levels of intelligence that they couldn't foresee anything.
