From Strategy Page (emphasis mine).
IEDs were used in Vietnam, but caused (with mines and booby traps in general) only 13 percent of the casualties, compared to over 60 percent in Iraq. The reason for this is one that few journalists want to discuss openly. But historians can tell you; Arabs are lousy fighters. Hasn't always been this way, but for the last century or so, it has. This has more to do with poor leadership, and a culture that simply does not encourage those traits that are needed to produce a superior soldier. In a word, the North Vietnamese soldiers and Viet Cong guerillas were better, and more deadly, fighters. Contributing factors include better training and equipment for American and Coalition troops. But most of the reason for the historically low casualty rates in Iraq have to do with Iraqis who don't know how to fight effectively.
