The numbers of Americans who "think WE are at war with islam" is irrelevant.
Because 100% of Islamists are ALREADY at war with the US.
It would be like saying only 60% of Americans "think we are at war" with Japan, 4 years after Pearl Harbor.
Japan sure thought they were at war with us!
Why are so many so-called "Americans" blind to the truth?
Because Americans have been indoctrinated by leftist academia and the leftist media in moral relativism for the past 50 years. We now have three generations of Americans living their lives with no moral absolutes, believing that we are no better than NORKS/NVA/ Che/Fidel/Iran/al Qaeda/ISIS...ad nauseum.
