One report said they were getting food and water. I would think, IMHO, that waiting is in the captain’s favor. The longer they have to think about it the better. But who knows? I’m not convinced the hostage negotiators know, for sure, any more about what works and doesn’t work than a person with good common sense does. Not to detract from them, but heck, we can’t even decide who among us will go berserk and shoot up the population.
American ships were not raided in the past (that I know of) They seem to have no fear of us now.
