Everything they’ve done since then is a fraction of the massive gift they gave the Chinese.
Heck, even the Chinese know what a joke this administration is which is why they basically captured Hong Kong, are trying to destroy Vietnam, extracting as much from Australia and India as they can in the past year while the going is good with the administration.
Also, comparing to Germany, a country with a population less than 20% of the US’s which has basically no standing army by design, and hosts massive American bases within it is a complete non sequitur.
Why don’t you compare to India, for example, which within weeks of a small border skirmish pretty much eliminated the entirety of Chinese digital companies from the country. Setting aside the wisdom of that decision, if you’re just comparing the actions taken by administrations, India has done far more in far less time that has been far more effective than throwing random tantrums after Xi refused to bribe your President enough.
