I had the pleasure of watching that committee meeting. I know what you're referring to.
My views are very much in the camp of Gordon Houlden's: We need to assess not just the professor and the institution they're coming from but also the field or discipline of research. The committee has looked at a list of these. ASPI has listed research areas. I would add polar science and so on, such as aerospace, rare earths and semiconductors. Even basic research into the properties of advanced materials and basic brain research are potentially problematic when China is now.... China has a policy for weaponry. They would like to develop weapons that meet the objective of winning without fighting. That's where brain research comes into it.
I'm not in the camp of being agnostic about where people are from or making researchers go through this process for every single country in the world. I also have a concern about the registry; this may be what it's going to look like. I think we should be focusing on the countries that we know are problems and on what's documented. China is certainly number one—and number two, three and four too.
