I guess I'm just saying we shouldn't just say "meh, it will be hard and we might not get the results that we want so lets not even consider doing something".
I don't think people are trying to shut down debate here. I'm open to "considering" doing anything. (Not that anything considerations made on an internet messageboard like this are going to amount to anything in the real world anyway.) I just expressed skepticism that this was the sort of situation in which an airpower only mission would be able to produce a desirable outcome. The Libya situation had several unique things going for it in terms of airpower being effective, and even that still took six months before victory was achieved! But I'm not an expert on this, so I'm open to being persuaded if there are good arguments on this.
