Here is a quote from one of the two students who did say Iraq was behind 9/11.
[Redacted]The writing is not entirely clear. I don't know what is up with "[redacted]." But it is clear that she believes we are at war in retaliation for 9/11.
The remaining student was writing a dialogue on the problem of evil. I've returned that paper and don't have an electronic copy of it, so I'm not going to get her phrasing right. Basically, though, one character puts forward the Leibnizian argument that all is for the best. Another character then says "even the attacks on the twin towers" and the first character, in a peculiar mix of relativism and panglossianism says that the attacks were good from the perspective of "the Iraq's"
