But if she was, it would be with good cause: the Russian government did conduct false-flag building demolitions to justify invading Chechnya and anchor Putin's rise to power.

From the article:

During this facial session she started quoting conspiracy theories, telling me that she thought 9-11 was purposefully created by the American government to make America hate muslims. “It’s real,” she said, “My son knows all about it. You can read on the internet.” I have to say I felt kind of scared and vulnerable when she said this, as I am distinctly American, and was lying practically naked in her living room.

Side note: what is "distinctly American"?
