The way I see it, the US is currently facing several fundamental problems:
An immature political culture: The United States is a relatively young country which hasn't really dealt properly with its its past - current events speak for themselves. At the same time, the country is running massive deficits spurred on by a combination of excessive expenditure *and* excessive tax cuts, and there is little political will in Washington to realistically address this imbalance.
No "Social Contract": There is a fundamental absence of shared values in the US. A lot of countries managed to formulate strategies for bringing the entire nation (education, health, business, employment etc.) forward during the 20th century. The German Wirtschaftswunder is a good example, as are the growth miracles in South Korea, Japan and perhaps even China after 1978. No such consensus exists in the US. Instead, political polarization has been increasing.
Political and military overstretching: The US has fallen into the same trap as so many other hegemons before it: It doesn't have the resources to maintain its global dominance in the long run, but it keeps trying nonetheless. Picking a fight with China in China's own backyard (the South China Sea is approx. 16,000 kilometres from the US) is currently the best example.
However, I don't see these as signs of a Failed State... But I find it somewhat unlikely that the US can successfully solve its massive domestic challenges and maintain its international prominence at the same time...
And I agree with the first article: None of this was caused by the coronavirus... It just made those winds blow even harder...
