We know at least two made it through. Underwear bomber, shoe bomber.
We also know pre-9/11 how common it was (non-existent).
We also know that they consistently fail audits. Though they've gotten better! Most recently they only failed ~75% of the time at detecting things auditors were trying to smuggle in, instead of the prior 95%!
So, yeah, by itself it doesn't. But we have enough data to make a pretty solid eval.
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.
They were replying to a comment which implied that the main risk of working for the TSA is dealing with bombs. But the TSA has never dealt with any bombs, so clearly that's not actually a risk of working there.
