Yes he did

Hitler did something wrong.

coward

he didnt pay his gas bill

He killed millions of common jews and not the Rothschild family, who funded him...

Yup, he didn't finish the job.

He didn't wanted to kill jews
He wanted peace with the anglo instead of crushing them
His country was suffering from a lack of demography in comparison of the USSR

That was his mistakes

Yeah he lost

Messing with the Soviets, obstructing his generals in leading the forces. Standard errors for paranoid kings

...

The only thing he did wrong was trying to attend art school.
