How so?
The Nazi's did not declare war on England and France. The Anglo-Allies declared war on them first. The Soviets never attacked us either.
So why did we fight?
Just trying to make a point here.
We lost about 1,400 at Pearl Harbor. We lost 3,000 on 9/11. Was Pearl Harbor a smaller scale and we should have sent Navy UDT teams to get Hirohito instead of going to war?
Well, you have to look at the probable outcome of all of these situations had we not intervened.
Had World War II not happened, Nazis would have continued a mass scale extermination as well as military occupation on 'civilized nations'. You could say the same thing about the Soviets with their legitimate nuclear threat. Japan's intervention could have also been a catalyst for even larger consequences to us in the near future.
Terrorists don't pose nearly the same threat. And we won't truly respond in some grand fashion unless they come from the middle east. It's just the usual military-industrial train moving forward because they occupy very fertile lands.
If we somehow had a terrorist from, Congo, let's just say, who did the same thing that the 9/11 attackers did, we wouldn't send out the troops as there is no oil there. Or we would, but would find an excuse to attack nearby fertile territory as well like we did with the Iraq/Afghanistan.
You should know pretty well by now, that our interventions are not truly for altruistic means, but instead, as an opportunity to collect resources.
