Calling 2009 a failure is a huge stretch that you're only making to rile me up because it was when Obama was in office. The economy was not effected in 09' and the disease was much less deadly in terms of transmission. (It didn't have a two week lag period).
I honestly don't care about the WHO. I don't care about them anymore than I care about the WTO, or NATO, or the UN. Yes, they are good entities to have and they promote nations working together, but they're not the ultimate body that makes the decisions for America. We have the CIA, Military Intelligence, the CDC, etc... for a reason. I would absolutely agree that many parties flubbed this, but oddly enough certain news outlets were actually reporting occasionally accurate and occasionally extremely important news stories. I know this because at the same time earlier this year (prior to March) my coworkers were saying "Trump says it's just the flu". I was telling them about reports we were hearing out of China about the extraordinarily troubling nature of the virus.
If a nobody engineer from the middle of America with no ties to China is getting more accurate information about the virus than our intelligence and health officials there's a huge problem somewhere. At the very least you'd expect certain people at those agencies to be troubled as they heard the same things. I mean, when China is building hospitals in a day just to deal with the number of patients you would think that our intelligence / health agencies might be directed to keep a close watch on the situation rather than just making decisions based on WHO tweets.
