Yes, Trump didn't have to deal with the fallout from COVID like Biden did. That's the reality.
To me, there are 3 issues at play when trying to excuse Trump's poor economic record as a 'Covid problem'...
- There were already signs that the US economy was in trouble before covid hit. Under Trump, economic growth and job creation in the first 3 years actually SLOWED compared to the last 3 years of Obama. Manufacturing had already been in a recession, and the trade deficit was increasing. And there was an 'inverted yield curve' (which is not the cause of a recession, but a sign that one is likely to occur soon). Had covid not been a thing, you still might have had a recession in 2020.
- Trump and the MAGAchuds like to claim credit for economic success in the first 3 years of Trump's term, even though trump had inherited an economy that was growing steadily under Obama (at which point the economy actually slowed). If Trump is going to claim credit for things that he had little role in assisting with, then he should get the blame when things go bad even if its something out of control. Sounds fair, doesn't it? You either accept credit and blame for everything, or you accept credit and blame for nothing.
- A pandemic is going to affect economic performance. But, Trump could have made the situation much less problematic. He could have kept scientists in china, which might have given western countries more information to work with. He could have taken stronger action earlier in the pandemic instead of claiming "it will be gone soon". His mismanagement made the situation much worse (both in terms of economic and humanitarian impact) than it should have been
Re: Trump not starting any wars...
It wasn't for lack of trying. Remember when he tried to start a war with Iran?
Remember when Trump abandoned the Kurds (long-time US allies)? Ah, good times...
Trump's solution to preventing war seems to be "let the foreign strong-men do whatever they want". The US was subservient to the Russians. Trump had a "love affair" with North Korea's leader.
