If they are terrified of China why aren't they doing more diplomacy or at minimum, not allow NVIDIA to sell their chips to them?

Sorry but the China scare tactics is just more cold war nonsense. The idea China as a serious threat to anyone in the world where you have the USA invading countries (invading Iraq based on lies), kidnapping Presidents (Venezula), assassinating various leaders (drone strikes), abusing democratic ideals (Patriot act, PRISM, parallel construction, using banned chemical weapons against their own civilians; the USA has been a huge threat against the world and itself for the last 25 years.

Diplomacy is too slow in the eyes of this administration, that's why we're in this predicament. It's not cold war nonsense nor is it anything new; our military and intelligence agencies have been working against China via geopolitical proxy wars long before the Trump administration. This is just a natural extension of the Peter Thiel "remove all bureaucracy, we're not moving fast enough" strategy.
