Colin Powell on those new troops John McCain wants to send to Iraq:
Before any decision to increase troops, "I'd want to have a clear understanding of what it is they're going for, how long they're going for. And let's be clear about something else. . . . There really are no additional troops. All we would be doing is keeping some of the troops who were there, there longer and escalating or accelerating the arrival of other troops."
We don't have an extra 30,000 soldiers to send to Iraq. All we can do is overlap their shifts.
