Helen's memory of Vietnam is as selective as that of any liberal's who insists he understood everything about the war but was never there. The war wasn't lost until the troops departed, dear. Remember?
More troops is also reminiscent of...let's see, what was that other country in the Middle East? Began with an "I" if I remember correctly. Helen doesn't, because we won that one. Which is why Vietnam came up instead of it.
As Tony Snow would say, ‘thanks for the Hezbollah point of view, Helen.’
