That's actually not true. The U.S govt. ran just such pandemic exercises in 2018 and 2019, put on by the Rand Corporation. The 2019 exercise was named Crimson Contagion. You really should read up on stuff before pontificating about shit you know nothing about.
Now, not saying the exercises went well....they didn't. Here's an article from Bloomberg about the 2019 exercise:
Virus Pandemic Exercise Got One Thing Wrong: the U.S. Response
Last October, about 50 national security experts gathered in Washington to role-play a global response to a frightening scenario: a pandemic sparked by a mysterious new coronavirus ravages the world, hitting North Asia, Europe and the U.S. especially hard.
The exercise got a lot right about the pandemic now sweeping the globe. It concerned a virus that’s “highly transmissible via direct person-to-person contact,” overwhelms available resources and kills more than 3% of those infected, roughly equivalent to the current rate, with a workable vaccine trial many months away.
One thing it got badly wrong: Those involved -- a mix of professors, international-relations theorists, intelligence experts and others -- assumed the U.S. would lead the global response.
Even after almost three years living under President Donald Trump’s “America First” doctrine, few in the scenario predicted the U.S. would initially play down the threat, refuse for weeks to heed lessons learned by other nations struggling with the outbreak and treat institutions guiding the response -- like the World Health Organization -- with suspicion and scorn.
“What’s happening now is much worse in the sense that the U.S. response has been even more ineffective than we would have assumed,” said Sam Brannen, a senior fellow at the Center for Strategic and International Studies’ International Security Program, who helped lead the exercise. “The president undercutting his own officials and his messaging -- I’m stunned by the scale of it.”
