The "false premises" were the Polish attack on a German radio station on the frontier. Vicious and uncalled for, leaving several German civilians killed.
Explain to me how this means WW2 was triggered on false premises.
I'm saying that at the time, that would have been the Wikipedia-explanation for the outbreak of WW2: Polish aggression. The article would explain the place and time for the aggression. It would document the victims identities, because there were real victims (killed by German commandos)
So, in the reality of 1939, if we were there, we were Germans, and we knew what was real, we would know that the war started because of Poland, not Germany. We would be saying that this war is about stopping Poland from terrorizing the German frontier with unprovoked attacks on civilians (as well as Czech mistreatment of Germans). Some would be saying that no, this war is carefully planned, and Germany intends to expands its borders to invlude Scandinavia, all of Eastern Europe - far into Asia, and it would sound absolutely insane.
I'm not saying we're "repeating history", I'm just showing you the possibility of such a scenario unfolding. You seem to think it unlikely. I see it as a human default. War for the sake of war, the money generated through war, both in terms of arms sales and rebuilding infrastructure afterwards. War must happen, and it is orchestrated to go on continously, even if civilians are proven again and again, to be perfectly capable of living in normal harmony - untill they are aggitated by manipulative politicians - who have something to gain from a war.
