Naw, I'm not talking about chancellor_Schroeder and the state of current affairs.

What I'm talking about is:

German invasion of Poland
('Since 4 o'clock, we are shooting back!')

German break of pact with Stalin
(It is said, that Stalin wouldn't believe early reports. He almost got lost for a few days)


Speaking in CIV-terms: a sneak attack and a major ROP-rape.
Everybody will be annoyed or furious with you for about a century - at least.
