Last I heard (about 1999), North Korea had temporarily agreed not to test the Taepo Dong-2 ICBM, but they do have it. Their mid-range Taepo Dong-1 medium range missile couldn't reach the US, but they successfully created and tested a 3-part missile (typical ICBM) instead of a 2-part missile (typical mid-range). The Taepo Dong-1 was mostly a success -- it failed to launch the satellite, but otherwise everything went well.

The -2, although untested, doesn't have much in it that is different from the -1. It's basically a conversion of the -1 rocket. But in rocket science, you never know until you test it.

The CIA thinks that the -2 would have limited accuracy hitting the continental US with a heavy payload (like a nuclear one), but Alaska and Hawaii are fair game. Of course, hitting San Bernadino instead of LA with a nuke has the same net effect!

Unfortunately, the Bush administration also ceased talks with North Korea -- the kind that generated the agreement not to test their ICBM.

Found this link detailing countries who have WMD. I don't know when the last time it was updated, but it looks decent research. Countries with WMD
