Is ether a common thread behind the san bernardino killings, the paris, killings the mali killings and boko haram nigeria killings?

Yes. As usual. Most ideological attacks these days are perpetrated by Muslims.

Yes, and ISIS has killed more muslims than any other religion. (I heard this on the news). Don't assume they don't kill their own religion, they do because their way of following the religion is different than how the good people follow it.

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.
