My pleasure! I was actually surprised by your gracious answer. And as a Canuck, I can tell you that you're absolutely right about the Fifth Estate. They did an episode on the War on Terror that was breathtaking.
It showed how the "war" was in fact an attempt to execute a neo-conservative agenda that had been in the works for years - known as the Project for a New American Century (PNAC). They've also got an episode on Putin's rise to power that I'm dying to see!
I can honestly say that what I know of Liz Cheney is quite recent. Thanks to her "rise to prominence," or whatever people want to call it, there are those praising her for doing the right thing (finally). But some journalists took the occasion to remind people of her record. I was surprised, I remembered some of what she'd done, but that I'd never realized who she was at the time.
