"Man, the Nazis should have lost WWII earlier! More people would have survived."
"But that doesn't NECESSARILY MEAN that any of the Holocaust victims or war casualties would survive, even if that's possible."
Most likely result is always what's implied on this site unless stated otherwise.
And I dispute that the most likely result is the US building an interstate highway down Baja with a POD more than a century before Eisenhower's project, or that Baja is seen as a great place to develop in general just because.
The idea of "build a railroad to the Sea of Cortez" makes sense - I'm not sure it's likely, but it's entirely feasible and desirable. But insisting that such developments would happen without giving any reason for the US to have any
interest in them is not feasible.
People treat it as if the US/Britain/Germany/Greece/Rome/whatever taking over is somehow going to mean that it does well, and speaking for myself, as an Austrophile (among other preferences, but I'm picking Austria-Hungary as an easy example of somewhere with some areas that were
far more developed than others - comparing the lot of Lower Austria or Bohemia to Galicia or Dalmatia , you'd think we were talking about two different polities instead of two parts of a single polity), that's not necessarily so.
Not government sanctioned Protestant missionaries obviously. Private groups.
Doesn't help. You want Mexican Catholics tolerating American rule, Americans - both the government and their fellow citizens - tolerating their beliefs is a very, very good idea.
