Tom Clancy in his book "The Sum of All Fears":

        The key to it, Qati knew, was whether or not the 
     Americans would put real pressure on the Zionists.
     They'd never done so.  They'd allowed the Israelis
     to attack an American warship and kill American
     sailors--and forgiven them before the bleeding
     had stopped, before the last victim had died.  When
     American military forces had to fight for every
     dollar of funds from their own Congress, the same
     spineless body of political whores fell over itself
     giving arms to the Jews.

"The Sum of all Fears" is a work of fiction.  This is 
Clancy's character Qati speaking.  It may or may not 
reflect Clancy's view, but it DOES show that Clancy
is aware of the Liberty attack and seems to have 
some understanding of the situation.
