The US, distracted by two other wars in which it isn't exactly wiping the field with the opposition, pretty much has had to say, "You're on your own," without actually saying anything. Oh, sure, we've said, "Bad Russia! Don't do that!" You may have noticed how well this works with a teenager when the parent has never been able to impose discipline in the past. It works about as well when the US says it to another nuclear power.
So, many American commetators have called for the US to "do something." I'm especially amused by Mr. Kristol:
The United States, of course, is not without resources and allies to deal with these problems and threats. But at times we seem oddly timid and uncertain.Yeah. Because we have so much leeway for action, here. I mean, what's a nuclear war?
One day maybe we'll start to realize that being the BBMFOTB isn't much fun if we can actually get beaten up once in a while because we don't have enough sense to keep fights from starting in the first place.
Until then, we'll get to watch the Georgians, Iranians, Iraqis, Palestinians, North Koreans, and a few more suffer.
