No, she mentioned it to point out that she was governor of a state that's a lot closer to a semi-hostile foreign power, and more thoughtful about the implications of that than would be the community organizer from Chicago (who had never been in charge of state police, let alone armed national guard installations). She wasn't presidential material, but nor did she claim that the right-next-doorness of Russia was an example of foreign policy experience. Her point was that when you govern a state with a huge energy and fishing and mining economy that's a stone's throw from a looming competitor in those same areas, it becomes part of your daily thought process. She's a clumsy speaker and has some wacky ideological quirks (mostly from having been raised in a religious family culture), but she wasn't wrong to point out, simply in passing, that having Russia and Canada as your next door neighbors while you're governor is different than having Indiana and Missouri as neighbors when you're a community organizer, whatever that actually is.
