The comments about the war games is interesting, because I have heard of these same results from defense blogs, and there the opinions are not usually so dismissive (though of course they're citing them to advance their point), in that a lot of people find the idea of small attack boats with a single gun a compelling strategy that the US could never use (for PR/morale reasons), but posit that these are the exact sort of tactics that others like Iran would be more willing to use effectively against the US.
