When you're dealing with specific historical events it's not just a matter of truth vs. logical consistency. The same issue comes up with ZERO DARK THIRTY. Boal/Bigelow are making a hash of a complex process and a very recent historical event in the interests of a unifying protagonist and a feminist theme. Would you have had Tony Kushner and Stephen Spielberg muck around with the events in LINCOLN in this fashion? The irony is that ARGO is a crowd-pleasing actioner, and ZD30 is a drab semi-documentary, but both distort history.
