 How do we know if they're Hamas or not? How do we know if those coming from Yemen are ISIS or the retooled ISIS or not? We have no vetting system, do we? Well, you know, that's a good point. And my saying is the vetting is only as good as the systems we're vetting against. And the fact is many of these countries don't have systems to vet against. You know, we first saw this after the withdrawal debacle.
