Good question. Where to put them, when the camps are full? How much money is it going to cost to imprison millions for life? Is there a more efficient solution?

… i did not speak out because premature Nazi comparisons diminish the Nazi crimes and are antisemitic.

We’ll have to wait for at least 5 million gassed before we can think about Nazi comparisons.

/s just in case.

They’ll do when they realize that’s the only way to fit 30,000 immigrants into a torture camp that can hold < 1000 inmates.

By May 2003, the Guantanamo Bay detention camp had grown into a larger and more permanent facility that housed over 680 prisoners, the vast majority without formal charges.

Yesterday, inspired by the news about mass depaorations, i watched a documentary on the Final Solution.

Among a lot of interesting things, one thing stood out to me: The original Nazis were afraid that the german people would not only reject genocide, but also reject the idea of jews (aka. their neighbors) being sent to brutal labor camps.
So they produced propaganda movies depicting the city Theresienstadt as a spa town. And then told the public that the jews would be sent there to be protected from the increasingly antisemitic public.

To lull victims into a false sense of security, the SS advertised Theresienstadt as a “spa town” where Jews could retire, and encouraged them to sign fraudulent home purchase contracts, pay “deposits” for rent and board, and surrender life insurance policies and other assets.

Nowadays, you can just tell the american people:

Hey, we are gonna send your neighbors to a torture camp. Great camp. Lovely camp. Most brutal camp of the world.

And they are like: Yessss, finally a solution to the migrant question.
