What would 1960s Nazi Germany actually look like?

[Max Sinister]

What about the vassal states in the West? Would the Nazis try to Germanise them or what?

They already've bitten off more than they can chew in the East - even if they made a compromise peace with Stalin, giving them a border along the Dniepr.

In short - would there be something similar to the "revolution of 1968"? Would young people rebel against their nazi parents just as IOTL, with much, much worse chances to win? Or on the contrary, would they become even more radical nazis?

That's an interesting possibility which, as far as I'm aware (but then I don't keep up with Nazi victory TLs), hasn't been explored. It's possible that, a couple of decades after victory, Nazi Germany has become socially stagnant, with a whole generation of young people either in university where they are fed a mind-numbing diet of stale propaganda, or vainly looking for a job. And some charismatic Party insider (perhaps a surviving Heydrich?) harnesses all that pent-up frustration to get rid of political rivals, only for youth unrest to grow out of control. Essentially, the Nazi version of China's Cultural Revolution.
