Exactly, it doesn't make sense. Two Japanese scientists to overlook whats going on. And plus, they didn't know it was near the end of the war. They were going to try and get back the upper hand I assume. Also, Im guessing they were murdered because Germany was gonna backstab Japan. Plus, it was a very secret operation, so I assume they were on radio silence or jsut didn't have one. Being intercepted was probably the last thing they wanted to have happen. And oh yea, they were shot in the back of the head, and they weren't nuclear materials. They found out they were for a super weapon from one of the people in the sub crew I think, obviously most of the people in the sub didn't know much about it.
