I have a hard time believing the rest of the developed world is making the decision foolishly
But based on what are they making their decisions on? It seems it's a political domino effect and CYA of not wanting to be the one nation who didn't ground it and has the next crash. Is there something specific that these countries know that we don't? There's an appeal to authority here that "the government must know what they doing" but ultimately these decisions are made by politicians who are looking to ease any potential blow back and mitigate the fall out should another crash happen.. plus.. the US is not in the most favorable light internationally right now, Boeing has picked a few fights with Airbus, Bombardier, etc., so...? Humans are generally emotionally weak people who cave to societal pressures with little (or no?) basis on fact
If you were at a gate right now to put your family on a plane and had a choice at the gate of putting them on a 737-700 or a 737 8max, which one would you put your wife and kids on
If I'm in the US, then I'll pick whichever plane isn't delayed and is scheduled to get me home faster. I trust US (and European, Australian, and Canadian) pilots know how to handle in flight anomalies.. and can actually still hand fly a plane out of trim.. or disable an errant system if it's causing odd behaviors. If I'm in Ethiopia.. guess what, I'm not flying commercially on a local carrier.
So many people say "wait for the facts" .. if we had a few Bonanza crashes due to a trim issue with some new Garmin upgrade nobody on here would be supporting the decision to ground the fleet.. there'd be critiques of the magenta line children (a few gratuitous Cirrus punches), etc., but there wouldn't be a call to ground. So where is that drive now?
All we know (currently) is that two third world airlines, with small fleets, one of which has an atrocious safety record, crashed the same type of plane under somewhat similar circumstances. These planes aren't fly by wire.. so if they're having trouble maintaining pitch there are only so many things that can cause that..
If I trust the pilots then I'll get on any V Tail Bonanza, MD11, 737 MAX.. etc.
