ITAR, like all US federal regulations codified in the CFR, have the full force and effect of the law. See the first couple paragraphs here for further explanation: http://library.law.unh.edu/AdminLaw

How do you know if something is subject to ITAR? The State Department has a big list. It's called the US Munitions List (USML). At the time Zimmerman said that, PGP probably wasn't on the list. But I assure you, blueprints of guns are absolutely on the list.

It wasn't on the list yet, proving his point about volatility.

> full force and effect of the law.

All decrees, from Hammurabi onward, have the same qualities.

What's really funny is that 2d blueprints of the m16 and others exist and are readily accessible. Also, the army has published in the past various handbooks for insurrection. The "improvised munitions handbook" comes to mind.
