shuttle diplomacy
What da two shysters in da "Emperor's New Clothes" story had to dispense a lot of in order to alleviate observers' suspicion as to why there was no thread on the weaving-apparatus on their looms.
All of da observing folks in da famous "invisible clothing" tale were absurdly trusting and easily-fooled (well, all except da "innocent little boy", of course), so da two swindlers had a very easy time of succeeding with their "shuttle diplomacy", at least until the parade was underway (by which time they themselves had likely slipped away with their ill-gotten riches and had long-since disappeared). In real life, however, representatives of various countries, governments, and ethnic/religious groups often have a much harder time coaxing trust and cooperation from da leaders and officials of da various territories dat dey hafta visit and work in.
