Yes; it does matter WHY they do things. It does not matter whether an opponent is evil or not; the Nazis were evil, and it definitely mattered WHY they did things.
Not at all, the Nazis were merely enemies to be beaten, not talked to, not negotiated with, they were to be ended no matter what they thought.
And they did not even attack the mainland of the US, why bother to give Al quida any sort of mental ascension or for that matter, why bother to quote the leader of the group responsible for the deaths of 3,000 innocent americans?
Actually, according the distorted reality these Ron Paul idiots live within, the Nazi's were perfectly justified.
We left the German people broken, poor and helpless after WWI. Our actions against them are far, far worse than anything we have done in the middle east.
Of course, these useful idiots don't have the testicular fortitude to defend the Nazi's like they defend Al Qaeda.
