Regarding jihadis, there is no point in taking a moral stance when dealing with an existential threat that rejects our notions of morality.
Regarding activities of WW2: WWI was waged exclusively against enemy troops. Germany was back for a re-match within 20 years. WW2 brought the war to the ENTIRE populace: the wealthy, the poor, the women, the children. We convinced the entire population that going to war against us was a terrible idea, and we haven't heard a peep out of Germany OR Japan in several generations.
The best way to pacify a country is to have it be the case that when a man speaks approvingly of war, his women scream at him in rage and terror.
Going back to the Global Jihad, they can send suicide bombers against us forever, as long as their money people keep financing the jihad. If you want to stop the jihad, it's necessary to go against the people who finance it, and the clerics that preach for it.
200 years from now, I want their children's children's children
to cower and cringe in fear whenever they hear the sounds of jet engines overhead
because their legends tell of fire from the sky.
I want them to hide in dark caves and holes in the earth,
shivering with terror whenever they hear the roar of diesel engines
because the tales of their ancestors talk about metal monsters
crawling over the earth, spitting death and destruction.
I want their mothers to be able to admonish them with
"If you don't behave, the Pale Destroyers will come for you",
and that will be enough to reduce them to quivering obedience.
I want the annihilation to be so complete that their mythology
will tell them of the day of judgment when the stern gods from across the sea
.. the powerful 'Mericans .. destroyed their forefathers' wickedness.
