The timeline is 100% accurate, anyone that follows international trade/news was aware of the dangers by the end of January.(I personally remember reading the papers about the virus's genome mid-January)

It seems we are in a period where most of our politicians would rather not take responsibility for dropping the ball and are trying to lie about observable and well catalogued recent history.

That's true. And the CDC did say not to wear a mask, and various other aspects of the US reaction are accurate. And the video doesn't even talk about faulty CDC test kits, banning of imported test kits, or other American own-goals in this crisis.

It does brush over some other details on the Chinese side, of course.
