'Dallas' hit a chord back in the late Seventies and Eighties because it was the age of greed: here you have this unapologetic character who is mean and nasty and ruthless and does it all with an evil grin. I think people related to JR back then because we all have someone we know exactly like him. Everyone in the world knows a JR.
These fallen heroes represent the character of a nation who has a long history of patriotism and honor - and a nation who has fought many battles to keep our country free from threats of terror.
