I would have, if I were president, I would have won Iraq in the same amount of time that we won because, essentially, we won here."

The U.S. formal involvement in the Vietnam War wasn't actually 19 years long"it was more like eight. But how can one expect Trump to know something like that, when he wasn't actually there? The president, son of a rich real estate mogul, evaded the military draft five times.
