Jesus, read a book. Maybe two.
"out technogy would be much better,”
How much of our nuclear weapons and/or space program was designed by people the Nazis would have shot? Our tech is better EXACTLY because Germany chased some of their best scientists out.
“because half of the world would work together,”
Even the Nazis didn’t work together. Hitler maintained control by playing his various followers against each other.
“there would be less crimes,”
No. Just no. Anything you enjoy like Free Speech would be a crime against the state. Look at Russia right now, where protestors are arrested for waving blank signs.
"less homeless people,”
I doubt this would be true. I do believe there would be fewer REPORTS of homeless people… But i doubt that the Nazi infrastructure would be better at providing for all.
“no political problems,”
A whole bunch of what you take for granted right now would become political.
“better goverment in the retarded fucking braindead eastern Europe,”
You mean genocide, opening the area up for colonization. No thanks.
“and whole world would be purged from those filthy fucking disgusting untermanschen that only bring chaos and disorder”
This is the real one, right? The rest was just also-wins. You want a purge.
