I see....
and you believe we don’t track shipping?
“and you believe we don’t track shipping?”
I know for a fact that we don’t track shipping in the way you seem to be saying. Every day ships arrive, and we have no idea what they’re carrying.
Do you think that when the Navy sees a cargo ship on the high seas they pull her over and inspect her cargo?
Unless they were seen loading a nuke on a cargo ship, that ship could sail unmolested to the vicinity of any of our ports. Once they were in the vicinity, they could increase speed and be inside the harbor before any of our people could react.
There would be no need to tie up and unload the nuke.
