You response was as I predicted, Sci
(even included the "obligatory" condescending remark) - well, almost: I expected that you'll go back to the 19th century to explain the war.
Personally, I think the Axis powers lost any right to claim they were justified or even excused in their actions when they began to conquer other nations.
Similarly with bin Laden and WTC.
You want to find motivations for the axis powers leaders/bin Laden? Fine
Just don't forget - they were not puppets - they made their own decisions (which you can't justify with causality chains).
And I doubt the victims from the concentration camps or WTC cared about what happened a decade ago.
And, in the trekverse - there's a big difference between propaganda and being able to morally justify one's position.
