Regarding Iran, we have of course been here before. People start running around talking about how "serious people" all understand the "dire" threat posed by some country or other, headed up by the latest incarnation of Hitler. What should be done isn't quite clear, but serious people understand that something has to be done. Pretty soon all "serious people" understand that we must have the "courage" to "face the threat" with the appropriate degree of seriousness, and all proposals of "what we must do" which don't involve the blowing up of nontrivial numbers of people are quickly relegated to the "unserious" camp.
Onward...
