Of the many ways Jews tried to get out of Nazi Germany and Europe prior to WW2, a few stand out in my mind.
1) Rafael Trujillo was willing to take in 100,000 Jews from Germany at the Evian Conference. He wanted right-wing agrarian minded Jews in particular (kind of ironic given how most Jews in Germany were urban professional SDP supporters) and it was part of his desire to "whiten" the population of the DR. Let's say here Trujillo just decides more immigration is better in general and is less picky about what sorts of folks come in - maybe he opts to increase the number of refugees over time to 150,000 or 200,000 people. Trujillo donated 220 square kilometers around the city of Sosua to the effort.
2) Dutch possessions in the Caribbeans (Aruba, Bonaire, Curacao, Sint Maarten, and Surinam) did not actually require formal visas to relocate to - just approval from Governors in the area upon landing. Some 2200 Jews fled from Lithuania to the Dutch Caribbean in 1940 with the support of the Dutch Consul in Lithuania via this method. The Dutch issue visas en masse in the Baltics.
3) Interior Secretary Harold Ickes was the person who pushed historically for relocating Jewish refugees to Alaska. Interestingly, immigration to territories and commonwealths was handled by the Interior Secretary rather than the the State Department (which was in charge of immigration at the time). Ickes, who oversaw the Virgin Islands, wanted to bring 10,000 Jews to the US Virgin Islands but was blocked by Breckinridge Long in the State Department. Let's say he's able to do this.
4) The tragedy of the MS St Louis, where some 900+ Jewish refugees tried to get off in Havana (and Cordell Hull tried to convince the Cubans to let them in) but Cuba denied them entry - then the US denied them entry as well. This trip would infamously go on to be known as the voyage of the damned.
5) In 1939, following the failure of the Evian Conference, Britain offered Guyana as a place for Jewish settlement. The area they were offering was considered for Assyrian resettlement (20,000 people) in 1935, so I imagine that at least that many people would be relocated.
6) Costa Rica at Evian was the only country other than the Dominican Republic to be open to letting in a large number of Jews from Central Europe. The Refugee Economic Corporation purchased a good amount of land in Guanacaste for the resettlement of Jewish refugees.
So, what if a great number of Jews from Germany, Austria, Czechia, and the Baltics were able to get out of Europe by relocation to the Caribbean?
What would be the knock-on effects for the places the Jews relocate to?
