If one looks at the history of military rocket technology and how far technology has come, I wouldn't assume, even if they didn't have the support we know they did, that they wouldn't have dangerous technology. German V2 rockets from 70 years ago were guided with little more than a gyroscope, simple clockwork, and basic calculus. I know something that reaches the homeland would be a lot more than that, but Hawaii, Guam, or any of our allies in the area could easily be targeted with 70 year old technology, most of which is public domain information.
