? Trump has literally made it a cornerstone of his presidency to extract the US from all foreign wars as quickly as possible and return to economic (bloodless) warfare e.g. Section 232 tariffs against China, renegotiating of trade deals.

Really. He was just nominated for the Nobel Peace Prize this morning. Genuinely curious why you think this.

As for COVID, he suspended all travel from China and Europe and likely stemmed the tide. As for the deaths - over half are in NYC and California, with both Newsom and Cuomo consistently making it a point to decline any aid offered by Trump. In related news, the CDC revised its death counts two weeks ago to say only ~9600 people died from COVID-19 alone. The vast majority of deaths were elderly (again in PA, NY, NJ, all states which forced nursing homes to accept convalescing COVID patients in the sole exception of the 14-day quarantine period mandated on exposure for the rest of the country.

What more would you have had Trump do to respond? He invoked the Defense Production Act to assure medical devices and vaccines could move through the pipelines as quickly as possible.

It's a novel pathogen. What do you think you can reasonably expect in terms of a federal government response (regardless of which side the administration aligns with)? If there was a simple answer this shit would have been over 4 months ago.
