Regardless of whether this particular case is true or not, given the crucial role of computer systems in so many key institutions, it seems to me extremely risky to trust Chinese suppliers not to try to compromise critical infrastructure. Then again, I understand that it could be argued that, if this is confirmed, to me it would seem quite rash from the Chinese, given that they would have known all along that such a scheme would be discovered sooner or later. It is one thing to plant a device as part of a spy operation, quite another to consistently compromise a whole supply chain. Whichever is the case, the national interest and commercial interests seem to be seriously incompatible with one another when it comes to outsourcing such critical infrastructure to China, this seems obvious to me, regardless of the China policy of who is in government in US.
