This is like trying to give someone confidence to jump out of a plane without a parachute by talking about all the people who've safely jumped out of planes with parachutes. It's BS: the situations are different, so the examples don't apply.
Step 1 of opening us schools in the US is implementing policy to get to the (lower) infection rates of those countries that have been able to safely open up schools. Unfortunately, there are US political factions that just want to skip that step and go straight to the end of the plan.
