I mean, where's the moral dilemma? They want to murder the whole world unless it agrees to slavery at their hands, AND they want to die for Islam.
In the immortal words of Captain Kirk, "I.HAVE.HAD.ENOUGH.OF.YOU!"
That is the key to all this.
Nazis = Berlin
Imperial Japs = Tokyo
Islam = Mecca
As I repeatedly said in 1979-80: "We want to kill them, and they want to die - see, everyone CAN be happy." You'll note that nobody listened.
