but I also grew up with a mother who was a history/political science major (my dad was a COBOL programmer for the VA decades ago). So the "politics" and "history" stuff was something she was actively following and discussing with me and my sisters and when she finally got cable back in the late '80s, my mom became a CSPAN junkie and made me into one too! 
The CSPAN/CSPAN2/CSPAN3 channels not only show Congress but also cover and broadcast many many conferences and policy-related panel discussions with respect to both domestic and international affairs. It is basically PBS on steroids (except without the "entertainment" / "lifestyle" stuff).
And with respect to Iran and this agreement specifically, there was quite a lot of discussion about it here on DU when the pact was being put together (I have been here since early 2008) and I felt so bad for Kerry and his million-mile "shuttle diplomacy" efforts to finally get an agreement only to see that cavalierly tossed away by 45!
