We can parse more deeply if we must. Hitler didn't march Jews to the doors of the ovens, but into them. The Iranians are the ones with sinister intentions in Mr. Huckabee's description, not Mr. Obama, who, again, is described as naive and feckless, not sinister and evil. Huckabee probably shouldn't have used the word "march" because it muddies his point. "Delivered to" or "abandoned at" would have worked better.
