I certainly think the victims of war and terrorist attacks are treated differently depending on race.
Look at the number of TVs programs about 9/11 we have over the years, looking at it from every angle.
Now consider Vietnam where the Americans sprayed Agent Orange all over the place to defoliate the trees to stop anyone hiding under them.
This has caused suffering for hundreds of thousands of Vietnamese people since, with deaths and cancer and deformed babies and so on.
But how many TV programs do you see about that?
9/11 gets far more coverage because it was in New York and mostly white "middle class" people died, not poor Vietnamese peasants.

I think actions like using Agent Orange (and other aggressive war like behaviour from the West) has caused much of this IS terrorist activity.
