You can have opinion on anything without knowing anything. This is what forums like this is about :). But if you want to give an informed opinion, you do need to understand the tech. For example, how do you decide what restrictions to put in export of nuclear power tech if you have no clue how it can be re-purposed to make a bomb?
International efforts against proliferation have been somewhat successful, even though they ultimately rely on politicians, not nuclear physicists. And in any case, a lack of knowledge regarding dual-use technology has never been the problem.
