JFK started Projects Mercury (single astronaut) and Gemini (two astronauts), though Gemini 1 flew in April 1964. Gemini flights were during LBJ's Administration, as were several Project Apollo (three astronauts) missions. All Apollo missions that landed on the Moon flew during Nixon's Administration. To the degree Presidents can be credited with the Moon landings, JFK, LBJ, and RMN share credit, and LBJ possibly a bit more than JFK.
But since Presidential accomplishments are being considered, JFK got us into Vietnam, and LBJ dug us deep into that mire.
As for Covid-19:
* It was China that did not notify the world about the Wuhan outbreak. Local doctors and government officials knew by mid December there was an outbreak in Wuhan, but it was only 2 or 3 weeks later that someone leaked word to the west about the outbreak;
* It was China that had two or more companies that sequenced this coronavirus' DNA before January 1, 2020, but did not inform the world until January 11th;
* It was China that had Wuhan doctors warning each other about human-human transmission during the 4th week of December, but denied to the world there was evidence of human-human transmission until January 20th;
* It was China that knew in mid December there was an outbreak in Wuhan, but allowed a mass banquet of some 40,000 people in Wuhan on January 18th and did not shut down travel out of Wuhan and Hubei Province until January 23rd;
* It was China's running dog WHO that in early January advocated against screening travelers and as late as February 29th advocated against travel shutdowns.
Do DUmmies ever acknowledge Biden's and Pelosi's and other Dem Reps' denunciations of Trump's China travel shutdown as racist, xenophobic, etc.?
Do DUmmies ever acknowledge Pelosi's and various officials in Dem-run cities' urging people during February and into early March to participate in public celebrations and activities and go about their usual personal public doings?
And, of course, all these Chinese and Dem deadly lies and underminings are documented in the two links in my signature. So, no, Trump did not take the US to the ICU.
