What in God’s name were they doing there to begin with?
A number of Latin American countries took in Jewish refugees before and during WW2. My friend Ruth ended up in Boliviare when she couldn’t get into the US or Cuba (the SS St. Louis was not allowed to dock there and was forced to return to Germany where the passengers were killed. Thank the anti-Semitic U.S. State Department for that and other anti-Jewish actions).
Ruth told me proudly that Spanish was her second language, not English, which she learned years later after immigrating to the U.S.
The anti-Semitic State Department was a prime mover in denying efforts by European Jews fleeing Hitler from getting into the US and Cuba. Other Latin American countries bravely let many in and saved thousands of lives, despite efforts by resident German Nazis and sympathizers to prevent it.
Not really being sincere about believing their ancestral promise... that’s what they were doing there.
They are going to get starved and persecuted out of some places.
Other places, like the USA, will help them go to Israel (Christians will do this).
