Didn’t another crazed German make the same threat about four decades ago??
BTW, it was a serious mistake to allow East and West Germany to reunite!
In 1978? Not sure what crazed German that might have been. German Chancellor in 1978:
"Helmut Heinrich Waldemar Schmidt was a German politician and member of the Social Democratic Party of Germany (SPD), who served as Chancellor of the Federal Republic of Germany (West Germany) from 1974 to 1982."
If you meant Hitler, he was Chancellor eight decades ago.
