It doesn't seem like the US could actually bounce back immediately after this, even with them being at the top. What more of those countries at the lower end right? Sure, the damage may not be as huge as what the US was inflicted but we've got to look at the scale instead. Plus, even if we did give at least 5 years to the banks, them bouncing back that fast seems to be out of the question. The vaccine hasn't even been made yet and there aren't really any positive news with regards to it after all, so it may actually take longer than that.
On a side note, Warren Buffett remarks the following
"In the end, the answer is: Never bet against America.”
Basically Warren Buffet, a key player of the 2008 financial crisis, believes that America can still standstill despite the overwhelming losses that the economy of the US has experienced and would probably experience in the next few years. Nonetheless, he hasn't really made any large moves recently, even with the stocks dropping quite hugely.

The IMF is not an international organization for nothing. The 2025 bounce back study of them surely have undergone serious study and investigation. They have been established long before we know it. We may see many people in the beaches and in the streets in America, it doesn't mean that their banks are not stumbling. Maybe they are just seeing the tip of the iceberg not the bottom. America may be a huge earning country but it also has lots of people to feed and over 1 million have alredy been infected.
I still agree that America is one powerful country. It will surely stabilize but not in a rapid way. This pandemic may last for more months to a year if a vaccine is still not found. So, once everything goes back to normal, America can rise up again easily.
