Finally, we need to learn the details of North Korean nuclear cooperation with other countries. We know that both Iran and Syria have long cooperated with North Korea on ballistic missile programs, and the prospect of cooperation on nuclear matters is not far-fetched. Whether and to what extent Iran, Syria or others might be "safe havens" for North Korea's nuclear weapons development, or may have already participated with or benefited from it, must be made clear.
For our own safety's sake, and that of allies like Japan and South Korea, there can be no compromises on these points.
My hunch is that Israel is taking a closer look at industrial sites outside of Deir al-Zur to see if they can see if anything looks Korea-like and what is going on with missile and weapons development.
This is speculation, but Western intelligence agencies have been suspicious for some time that Korean technology is working its way to Syria.
