i remember seeing an NPC conference before on a similar topic which i was watching live on cnn.com ... after 30 seconds it switched over to some stupid political BS that had nothing to do with it.
watched it. they showed 3 testimonies.
the alien's behavior is strange. why would they disable a few nukes that could be easily activated again, other than to send a simple message: "we're here, this is what we can do, you are playing with fire"
