ISIS audio urges Muslims everywhere to kill 'unbelievers' why doesn't US/UK/France nuke already?

That verse is about non Muslims who are attacking the Muslims. It is forbidden for a Muslim to engage in offensive warfare. And no one that blows themselves or other people up while screaming 'Allahu Akbar' is getting 72 virgins in Jannah.

The Qur'an is very clear about what will happen to Muslims who kill themselves and/ or other unjustly (i.e. Innocents) and/ or with aggression. Holy Qur'an 4:30: And whoever does so unjustly and in aggression, We will drive him into a Fire.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
