What could an alternate 2020 looked like? For a while, in January and February, it looked like the US was headed for a real war against Iran (presumably with Saudi Arabia doing some of the fighting). The illegal airstrike that killed General Solem Soleimani could have easily set the Islamic Republic off. It would have resulted in thousands of civilian deaths, but the US had committed an act of war on top of Iran’s provokation of having their top general in Iraq. Instead, Iran fired warning shots at US forces (which still caused concussions and ruptured eardrums, which Trump didn’t care about, but that’s another story).
Another alternative 2020 would have been a close, but not unexpected re-election for Donald Trump. After all, we didn’t know at the time, but Trump had been gaining in popularity throughout his residency, particularly with Hispanic and Black men. Against a old, non-confrontational Biden, he probably would have won.
And in yet another alternative 2020, the SARS-CoV-2 pandemic still happened, but Trump took it seriously and let a panel of public health experts set a national policy, keeping the death toll under 100,000. His good handling of the pandemic would also result in a re-election victory.
