In the book, Zinni writes: "In the lead up to the Iraq war and its later conduct, I saw at a minimum, true dereliction, negligence and irresponsibility, at worse, lying, incompetence and corruption."
“I think there was dereliction in insufficient forces being put on the ground and fully understanding the military dimensions of the plan. I think there was dereliction in lack of planning,” says Zinni. “The president is owed the finest strategic thinking. He is owed the finest operational planning. He is owed the finest tactical execution on the ground. … He got the latter. He didn’t get the first two.”
Zinni says Iraq was the wrong war at the wrong time - with the wrong strategy. And he was saying it before the U.S. invasion. In the months leading up to the war, while still Middle East envoy, Zinni carried the message to Congress: “This is, in my view, the worst time to take this on. And I don’t feel it needs to be done now.”
But he wasn’t the only former military leader with doubts about the invasion of Iraq. Former General and National Security Advisor Brent Scowcroft, former Centcom Commander Norman Schwarzkopf, former NATO Commander Wesley Clark, and former Army Chief of Staff Eric Shinseki all voiced their reservations.
