Art, I think there's an important idea to consider along with the 'paper tiger'.
We also run the risk of being the 'headless monster'. That is, if we appear to be a stop-at-nothing, completely unreasonable, fingers-in-ears nation, what incentive do others have in negotiating, compromising, or even talking? The only thing to do with monsters is kill them.
In general I think it's very productive in deciding a position, to try the shoe on the other foot, so to speak. What if the Arab countries, for example, decided they dare not become 'paper tigers' either?
