Well I guess to be fair it would be a matter of Homeland Security. Either way, there are agencies who's directives are about dealing with international fraud. Global commerce comes with global agreements.

1) There's certainly cards coming from non completely sanctioned countries. This means legal pathways.

2) If fraud is prevalent and these numbers can be tracked it makes for better policy decisions. It's not uncommon knowledge that we don't have the best privacy and security. This is at least ammo to do something about it.
