Re: "the company presents a national security risk"
They do not 'need' to buy chips from Broadcomm, Intel or whatever. Its a commercial decision.
A couple of days ago Huawei's chairman had a lengthy interview with a journalist from Yahoo Finance. Its worth reading the transcript.
The only risk Huawei poses to the US is that it threatens US hegemony. Our government's reaction to this threat has the potential to cause irreversible damage to large segments of the US's technology industries. If you work in this area you'd understand this but instead we get a lot of comments from the "Brandy and Cigars in the War Room" mindset crowd that are based on a fantasy world from decades ago. (Its no coincidence that they're trying to push a rehash of "Top Gun"......I expect it will be yet another version of "Red Dawn" next....its about all we're fit for these days.)
