there's no value add - other countries aren't really concerned with security theatre to the extent that the US (maybe UK?) is. witness the difference between screening at e.g. international airports outside of US/UK and then additional necessary screening for US bound flights. perhaps, though, that makes it a great export opportunity there, similar to arms exports: US law will mandate that these scanners are minimally required for inbound flights, other airports pick them up in order not to lose US flight slots.
