The fact is that Trump is not a scientist, and he was thinking out loud about things he probably should have kept his mouth shut about--but rarely does he do that on any topic.
Yeah, it was also a really short bit, a 20 second minute filler seemed to be taken quite out of proportion by all the media...
The People's Republic of China should be sanctioned due to the outcome of their incompetence and selfishness act. They should be the one who started the lockdowns and not allowing their citizens to go around the world.
Every other country was quite slow to react (South Korea seemed quite quick but still not entirely).
The UK and a lot of Europe already had stockpiles due to political tensions that could arise from brexit in the immediate term.... China should've implemented a lockdown sooner but as soon as other countries knew about the virus I think they shouldn't shut their borders to anything passengers and send an alert to their citizens in other countries to get in contact with an allied embassy there and their insurance provider...
