As the eminent Arnold Toynbee said, "Civilizations die from suicide, not by murder".   Here, Arundhati Roy carries her Post-Modernism to its logical suicidal ends -

...the longer you stay [in places like Iraq], the more you're enforcing these tribal differences and creating a resistance, which obviously, on the one hand, someone like me does support; on the other hand, you support the resistance, but you may not support the vision that they are fighting for. And I keep saying, you know, I'm doomed to fight on the side of people that have no space for me in their social imagination, and I would probably be the first person that was strung up if they won. But the point is that they are the ones that are resisting on the ground, and they have to be supported, because what is happening is unbelievable.

She'd rather side with the barbarians who'd "string her up" than be accused of supporting a Western world which provides her an unimaginably comfortable lifestyle.   I suppose that lets her to die with a clean conscience.  So be it.
