McCain Foreign Policy Advantage? Listen Closely

I can’t resist, having seen a recent ad featuring the candidate himself, talking about his attitudes toward war. In it, John McCain refers to the five years he spent as a POW in Vietnam. For all that time spent there and his vaunted foreign policy experience, why can’t he pronounce the name of the country correctly? The letter “a” in Vietnam is pronounced as in “ah” or like the “o” in kingdom; it is not pronounced like the “a” in Sam or “wham.” Are there other country names he has problems with? Will that pose embarrassing problems in diplomacy? Is this indicative of the edge he claims over Obama?
