James Bond represented the Cold War. Sherlock Holmes another icon of not just detective stories but late Victorian era. Jack Ryan?? Post Cold War? Wouldn’t an iconic literary character be one that has universal readers? Did Clancy have that? He had devoted readers but his technobabble could be a turnoff if you were not interested in military and NSA technology. Actually unlike Fleming, Clancy’s Ryan was almost secondary to technobabble. For Fleming everything flowed from Bond. Same with Doyle his character was the center. Clancy not really.
I confess I used to read Clancy’s novels pre2000 but Ryan was not the main reason. Most series you read it for the main character with Jack Ryan he just seemed secondary.
Iconic or not? I say no. Maybe in twenty years but not now.
