And what I'm saying is that these huge maritime companies like P & O hire subsidiaries and sub-contractor type companies from around the world to do much of the work for them. And it's these smaller (foreign) companies who hire their own people, from God-knows-where, and they do their own background checks on these foreign workers without being required to have them vetted by U.S. security. This is what I have heard from a Merchant Marine Captain whose in the field well over twenty years.
(Cpt. Kelley Sweeney, Merch. Marine - Google him if you'd like, he's a very knowledgable source on this topic and has written about it. He's also the editor of a big Merchant Marine publication).
GW will be long gone before we find out exactly how bad this deal actually is.
