More on the ending
Starting a new thread because the other threads discussing the ending are getting hung up on would they - could they - should they have killed him.
Apart from the fact that the CIA, in such a situation, would have taken control of the situation - putting their own man as ghost writer - long before TG got involved, the big problem with the ending as film is timing.
TG could have made the discovery at any time - even before Lang's death. He certainly had weeks, at least between the death and the book launch to make the discovery and disseminate the information.
And yet we are lead to believe that, despite the CIA considering the information so important that they were prepared to commit at least two murders, they did nothing other than have a hit team standing by to perform a potentially difficult and very public assassination AFTER the most likely event at which he (or those he had told) would release it.
Effectively, the CIA plan was this:
We know that there is information there and we know TG has had access to it for some time. He could already have made the connection or he could at any time in the future. We can't let this information get out but we won't kill him quietly out of the public view now. No, what we'll do is have a hit squad available 24/7 so that the moment we know he has figured it out we can have him killed - possibly very publicly, within seconds.
Although we're perfectly happy to kill someone right out in the open on foreign territory we'll take the risk that he'll tip us off to the fact that he's got the information BEFORE he takes any steps to disseminate it even though he knows that his predecessor was almost certainly murdered.
Really, this is so utterly brainless as to be completely indefensible.
