I'm not saying there are no potential solutions to the problem. I'm saying it's not "just as easy". With some of those types of smugglers mentioned, you have to keep them quiet (but more or less unharmed, I would expect) as well as alive, for at least days, and maybe months if there's a snafu. Or accept that some containers aren't going to make it.

It's not clear to me what the challenges are with smuggling radioactive material, or how good detection protocols are. That doesn't mean I can't think of any, or solutions to same, but it means that I expect there are at least some consequences I'm not thinking of, and it's certainly not as easy as some sealed, inert cargo.
