I wouldn't comment specifically on Huawei. I would say that we've been dealing with issues of supply chain risk since...gosh, I wouldn't want to say how far back in history. Certainly since the dawn of the crypto-analytic platform in signals intelligence, supply chain problems have been paramount.
There's a diminishing marginal rate of production if you decide you're going to try to pursue every single chip in the universe to make yourself secure. For certain elements of, say, a national security community or the public safety community, I think it's perfectly reasonable to say, “We are going to now manufacture a certain number of chips on our own”. But the cost is quite significant, and it alters how people do things economically. I don't think you could possibly do so in any kind of global way across sectors for an entire economy. You could probably do it for a number of subsectors.
