It’s clear that Israel felt that there was some sort of threat, but they are not talking. That being said, if there is a faceoff between those who are completely batsh$# insane and always wrong and those who are sometimes insane, and usually wrong, I’ll go with the latter.
Syria has no background in nuclear weapons technology, but I could see them getting improved chem/bio warheads from the DPRK, as they do have active programs there, at least on the chem side.
