The average German was a nice person. Even in the 1920's this was true.
That didn't stop looney toons from gaming the system, seizing power, and causing the deaths of fifty millon people.
The Iranians I've met are nice people. Too bad, then, that the Iranians in Iran have allowed their nice country to be overrun and ruled by religious fanatics who deny the German Holocaust happened and who beleive another nation should be erased from the earth....while they themselves have been financing a decades long program of international terrorism.
So, AGAIN, your attempt to establish moral equivalency for Iran's leadership has failed.
You need to explain, in detail, why you wish the leaders of a nation that promotes international terrorism should be allowed to finish the nuclear weapons project that's nearing completion.
Denying they have the weapons program is not an option, unless you're going to argue that even if they had the weapons, any attempt to launch them would cause the weapons to fall off the edge of the earth to bother Atuan, the Great Turtle.
