Get the Foreign Ministries of major countries, like UK, Japan, Korea, Germany, France, India, etc., to issue TRAVEL ADVISORIES on their official webpages (like the State Department does on it), warning their foreign nationals that they may be subject to intrusive and rude if not obscene physical treatment by US aiport authorities on the occasion of their US visit, and that they may also enter foreign data base (i.e. USA and not their home country) in visual form, as being nearly naked. Also that challenging US airport authorities, even politely, could land one in a US prison or with a hefty fine.
I know some countries that will be ready to do this very, very soon. When that happens, all hell will break loose. The s-pot can be further stirred that when these advisories appear, the foreign press in those countries also do print and TV stories on the TSA "overreach". It will spread like a grassfire.
Wouldn’t Russia, China, Greece, the 57 Islamic states and Central/South America love that idea?!

the economic impact would be very traumatizing.
