Yes, General Tommy Franks is very insistent on how they are our friend and allie in the WoT. Of course I'm sure your first hand knowledge and experience far exceed his.
The processes of port security are being implemented irregardless of who owns the port operations. As far as bad stuff getting into this country, that part of the scrutiny gets done at the ports of origination. Nothing gets out of a port without a thorough top to bottom check with instruments and X-Ray. Ships will stay even if the offending radiation may be a ceramic paint that has some kind of residual radiation in the clay that was used in it. And we have no idea of what are the capabilities of our spy satellites. If you want to know about infiltration, read Ann Coulter's Treason. In this case, the infiltrators today may have a darker shade of skin than Soviet spies (If they are Islamo terrorists). Infiltrators without a strong security operations, can get in irregardless of who owns the port operations. And smart infiltrators will outsmart any security that uses race as a indicator of who to watch. Most of the port security is done by the U.S. Coast Guard. I am sure the Navy Department does close background checks on its Officers. The U.S. Coast Guard has a few good men. We must also try not to let Hollywood fantasy films shade our fears of some kind of Terminator detonating a container in New York Harbor with his cell phone. That's not going to happen. We have the technology Captain.
