You might want to reword that.
There is something to be said for maintaining communications, preferably on a background level, with national leaders like Ahmedinejad, the head of Syria, or even nutballs like the leader of North Korea who still have something to lose.
But I don't think the leadership of al Qaeda falls into that category. There has been communication with other factions that have been working with al Qaeda, and this has been fairly successful so far in turning them around, but I think someone like bin Laden or Zawahiri are lost causes.
