Both the underwear bomber and shoe bomber boarded flights overseas (Amsterdam and Paris respectively) -- so no TSA involvement.

The TSA has operated overseas before, but probably not in these countries.

If they see a country isn't up to their standard, I think they either show up to implement it for flights headed to the US or at least consult with the nation.

Underwear bomber was Saudi intelligence/CIA, for the reader's info.
