I just can't get behind the idea that Brody cares more about punishing the VP for war crimes and because he lost someone close to him "Issa" than he cares about his own kids and how his actions would ruin their lives forever. I don't care about the whole "Gettysburg" trip where he explains standing up for what you believe...the fact he puts Issa above his own kids is tragic and doesn't really do it for me considering the character he plays.
It no longer really makes sense that he is working for Nazir...since he obviously cares about his daughter, and his daughter talked him out of committing an act of terrorism. I guess they have his suicide tape now as leverage, but still...
I think the story of why Brody is working for Nazir when put together with the love he has for his children just doesn't do it for me...but hey, it's TV fiction so I can't really complain.
I certainly wasn't complaining during all of those 24 seasons that I found absolutely riveting.
